Federal Circuit Further Refines Design Patent Analysis Post-Egyptian Goddess

Over the last few months, the Federal Circuit has issued three precedential opinions that provide further guidance (or some might say misguidance) regarding the analysis of design patents in the post Egyptian Goddess era.

Claim Construction and Functional Elements in Design Patents

NO INFRINGEMENT

On March 9, 2010, the Federal Circuit decided David A. Richardson v. Stanley Works, Inc. (2009-1354) and addressed the manner in which functional elements of a design patent should be addressed in claim construction and infringement of design patents. The patented design and a representative drawing of the accused "fubar" product are illustrated above. The district court construed Richardson's design patent by noting that what was claimed was that "shown and described in the '167 patent." The district court then continued by identifying those elements that were ornamental and excluding those elements that were deemed functional. Having so construed the claim, the district court held that the accused "fubar" did not infringe Richardson's design patent.

The Federal Circuit affirmed. With respect to claim construction, the Federal Circuit rejected the Richardson's position that Egyptian Goddess effectively overruled cases such as OddzOn Prods. v. Just Toys, Inc., 122 F.3d 1396 (Fed. Cir. 1997) where the court held that "[w]here a design contains both functional and non-functional elements, the scope of the claim must be construed in order to identify the non-functional aspects of the design as shown in the patent." The court further stated that "[a] claim to a design containing numerous functional elements, such as here, necessarily mandates a narrow construction." The court went on to discount the contribution of a myriad of functional elements in the claimed design and agreed with the district court's conclusion that "[f]rom the perspective of an ordinary observer familiar with the prior art, the overall visual effect of the Fubar is significantly different from the Stepclaw [patented design]."  From this ordinary observer's point of view, this holding had way more analysis than was needed to affirm - the two designs shown above are just too different.

Invalidity of Design Patents
On December 17, 2009, the court decided International Seaway Trading Corp. v. Walgreens Corp. (2009-1237), and held that the test for anticipation of a design patent is the same as the test for infringement, which is the "ordinary observer" test. The point of novelty test, abolished from the infringement analysis in Egyptian Goddess, is now a thing of the past in the validity context as well.  As a result, a piece of prior art need not be exact to anticipate a design patent claim, it must only satisfy the standards of the "ordinary observer" test.  "Just as 'minor differences between a patented design and an accused article's design cannot, and shall not, prevent a finding of infringement,' [cite omitted] so too minor differences cannot prevent a finding of anticipation."

Although dicta, the International Seaway court also discussed the test for obviousness of design patents. Here, the court stated that '[f]or design patents, the role of one skilled in the art in the obviousness context lies only in determining whether to combine earlier references to arrive at a single piece of art for comparison with the potential design or to modify a single prior art reference. Once that piece of prior art has been constructed, obviousness, like anticipation, requires application of the ordinary observer test, not the view of one skilled in the art." This sounds like something new. Indeed, in setting out this proposition, the court did not cite any precedent. Further, the "ordinary observer" test in this context may be viewed as inconsistent with the language of 35 U.S.C. 103(a) which states that a "patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains." As noted above, the discussion regarding obviousness is properly viewed as dicta.  It will be interesting to see how the law of obviousness of design patent claims develops in future cases, or if it become essentially moot in view of the broader play that the "ordinary observer" gives to the anticipation analysis.

Will differences in the insole design prevent anticipation?

The subject matter in Int'l Seaway was a design for foam clogs. The Federal Circuit held that the district court incorrectly omitted certain features (the insole design illustrated above) from its validity analysis, based on whether those features would be visible during "normal use." The Federal Circuit held that "normal use should not be limited to only one phase or portion of the normal use lifetime of an accused product," such as the time when a shoe is being worn. Instead, "normal use in the design patent context extends form the completion of manufacture or assembly until the ultimate destruction, loss, or disappearance of the article." Noting that the insole design depicted in the patent would be visible at various points in the life cycle of the article, the Federal Circuit found that it was an error for the district court to ignore these features in the validity analysis simply because they were not visible when the shoe was being worn. The court remanded for the district court "for further proceedings on the limited issue of whether the differences in the insole patterns between the prior (Crocs) are and the patented designs bar a finding of anticipation or obviousness." This remand order is somewhat troubling. As noted in J. Clevenger's dissent, "the ordinary observer test requires assessment of the designs as a whole." "[T]he differences in the inner sole designs must be appreciated in conjunction with all of the design differences." J. Clevenger aptly concludes that "[p]artial judgments of anticipation on segments of a design prohibit assessment of designs as a whole, in violation of long-standing law... ."  Although preaching a "design as a whole" analysis, the majority's holding and remand order is clearly fostering an approach that will encourage a district court's "dissection of a design as a whole into its component pieces."

Claim Construction and Domestic Industry for Design Patents
On February 24, 2010, the Federal Circuit issued its opinion in Crocs, Inc. v. Int'l Trade Commission (2008-1596). In this case, the court reversed ITC determinations of no infringement and no domestic industry of Crocs' design patent. Despite earlier warnings from the Federal Circuit that construing a design patent claim in words, rather than by simple reference to the figures, was a risky proposition, the ITC issued a narrow claim construction that focused on areas of difference between the claimed design and the accused product. The Federal Circuit criticized the commission’s "concentration on small differences in isolation distracted from the overall impression of the claimed ornamental features." Instead, "[t]he proper construction requires a side-by-side view of the drawings of the [patent design] and the accused products." Despite some obvious differences apparent (to me at least) in some to these comparisons, the court found that "these side-by-side comparisons...suggest that an ordinary observer, familiar with the prior art designs would be deceived into believing the accused products are the same as the patented design."  Unfortunately, the Federal Circuit opinion does not reference the "prior art designs," so it is not clear how to evaluate the differences between the claimed design and the accused products.  (An example of the images shown in the Federal Circuit opinion are shown below in the first two images (side view).  The top view illustrated below as compared with Fig. 6 of the patent where not part of the Federal Circuit's side-by-side comparison.  I don't know that I would be deceived here, but I suppose that reasonable "ordinary observers" are free to differ.) 

"NEARLY IDENTICAL" - DESIGN PATENT INFRINGED

With respect to the domestic industry requirement, the court found that Crocs' products were indeed within the scope of the design patent and those products therefore satisfied the "technical prong" of the domestic industry requirement.

False Marking Revisited - The New Wave of Patent Prospecting Is On

In my December 30, 2009 post, I speculated that “the holding in the Forest Group may still create an incentive for more qui tam actions being brought for false marking. After all, even a fraction of a penny applied to a billion items can still amount to millions of dollars in potential recovery. [The holding in Forest Group] may invigorate a new class of litigation prospectors… .” A short two months later, it is clear that this is indeed the case.

Based on case filings as reported by Justin Gray, on his Gray on Claims blog, ( http://www.grayonclaims.com/false-marking-case-information ), during the period from September 5, 2007 through November 13, 2009, only ten cases were filed alleging false patent marking. In the two month period since December 30, 2009, at least 69 false marking cases have been filed. These cases have been filed by twenty two (22) different plaintiffs. One plaintiff, Mr. Simonian, is the named party in 28 cases, another, Dr. Hollander, is the named plaintiff in seven cases. Most, if not all, of these cases are based on a manufacturer marking product with patents that are now expired.

Clearly, false marking is an area that will continue to be exploited by a new breed of plaintiffs during 2010. As I said just before the new year, given this “new class of litigation prospectors, the time is right to review your patent marking and clean up any marking that may no longer be applicable.”

Fine for False Marking: Per offense = $$ Per Article

False marking gained a bit of publicity this year with a number of qui tam suits being filed against companies who allegedly violated 35 U.S.C. 292 by marking products with expired patents. (See e.g., Public Patent Foundation, Inc v. Cumberland Packing Corp, 09-cv-04360. S.D.N.Y.; Perquignot v. Solo Cup Co., 07 cv 897, E.D.Va.).

The elements of a false marking claim are fairly straight forward: (1) marking an unpatented article with the word “patent” or other indication that the article is patented and (2) intent to deceive the public. Under Section 292, the penalty for false marking is that the party “shall be fined not more than $500 for every such offense.” Section 292 also includes a qui tam provision that provides that “any person may sue for the penalty, in which event one-half shall to the person suing and the other to the use of the United States.” What was unclear, until now, was whether “every such offense” was to be applied on a per article basis or as a single fine for a continuous act of marking. The difference is clearly huge. Would a defendant such as Cumberland Packing Corp. be facing a single fine of up to $500 or facing this fine for each and every one of the billions of packets of Sweet n’ Low that it sold?

In The Forest Group, Inc. v. Bon Tool Company, 2009-1044, the Federal Circuit resolved the debate and held that “per offense” means per article marked, and not a single fine for continuous false marking. In tempering this holding somewhat, the Federal Circuit noted the statute requires a fine of “not more than $500” and “by allowing a range of penalties, the statute provides district courts the discretion to strike a balance between encouraging enforcement of an important public policy and imposing disproportionately large penalties for small, inexpensive items produced in large quantities. In the case of inexpensive mass-produced articles, a court has the discretion to determine that a fraction of a penny per article is a proper penalty.”

Even with the guidance provided that would support fines of only “a fraction of a penny per article,” the holding in the Forest Group may still create an incentive for more qui tam actions being brought for false marking. After all, even a fraction of a penny applied to a billion items can still amount to millions of dollars in potential recovery. With the new year approaching, and new guidance from the Federal Circuit that may invigorate a new class of litigation prospectors, the time is right to review your patent marking and clean up any marking that may no longer be applicable.

Reflections On The Erosion of Method Claims

It wasn’t that long ago that patent practitioners held the view that means-plus-function claims were the broadest and best way to protect an invention. Over time, many learned (the hard way) that this isn’t true anymore. With means-plus-function claims being construed narrowly in view of the specification, it became increasingly popular to include method claims to cover the process taking place in the described apparatus. After all, what could be better than not being limited by any structural limitations? Well, as it turns out, the last couple of years have not been particularly kind to method claims.

Patentable Subject Matter:

Today the Supreme Court is hearing oral argument in Bilsky, a case that many feel will significantly redefine the scope of patentable subject matter for method claims. (And providing motivation for today's musings.) Bilsky is the culmination of at least a two year trend at the Federal Circuit where 35 U.S.C. 101 has been increasingly applied as the basis for denying patent protection for claims directed to methods. The Federal Circuit's now infamous “machine or transformation test,” set forth in Bilsky represents a considerable narrowing of patentable subject matter for methods. Clearly, those post-State Street feel good days for business method patents are behind us for the moment. But, Bilsky and Section 101 is a subject all its own (and the subject to countless other posts and articles), so lets move on to some other issues.

Infringement of Method Claims

Divided Infringement:
Last year, in Muni-Auction v. Thomas, 532 F. 3d 1318 (Fed Cir. 2008) the Federal Circuit addressed the issue of infringement of a method claim when two or more entities were required to act in order to perform all of the steps of a claimed method. In the patent in dispute in Muni-Auction “at least the inputting step of claim 1 is completed by the bidder, whereas at least a majority of the remaining steps are performed by the auctioner’s system.” Id. at 1328. In finding that there was no direct infringement (and therefore no predicate for third party liability based on inducement or contributory infringement) the Federal Circuit looked to the relationship between the bidder and the auctioner. The court held that:

Accordingly, where the actions of multiple parties combine to perform every step of a claimed method, the claim is directly infringed only if one party exercises “control or direction” over the entire process such that every step is attributable to the controlling party, i.e., the “mastermind.” [Citation omitted] At the other end of this multi-party spectrum, mere “arms-length cooperation” will not give rise to direct infringement by any party.

* * *
Under BMC Resources, the control or direction standard is satisfied in situations where the law would traditionally hold the accused direct infringer vicariously liable for the acts committed by another party that are required to complete performance of a claimed method.

Although the holding in Muni-Auction is consistent with earlier cases on the issue of divided infringement, such as BMC Resources v. Paymentech, L.P., 498 F.3d. 1373 (Fed. Cir. 2007), this decision seems to raise the bar regarding the nature of the relationship required in order to find liability under a “divided infringement” theory. Under Muni-Auction, to establish infringement of a method claim under a divided infringement theory, one must not only show that the entities involved perform all of the steps within the scope of the claim, but must also establish a close legal relationship among those entities.

Steps performed Abroad:

In August, an en banc Federal Circuit addressed whether a method claim could be infringed under 35 U.S.C. 271(f). The Court held that “because one cannot supply the step of a method, Section 271(f) cannot apply to method or process patents.” Cardiac Pacemakers v. St. Jude Medical, 2007-1296 (Fed. Cir., August 19, 2009). The court further held that “271(f) does not encompass devices that may be used to practice a patented method.” Id. at 30. Thus, a device built in the United States that is capable of performing a patented method, but does not actually perform that method in the United States, does not infringe a claim to the patented method under 35 U.S.C. 271(a) or (f). Again, without direct infringement, there is no basis for assertions of third party liability based on threats of inducement or contributory infringement.

Going back a few years, in NTP v. Research in Motion, the Federal Circuit held that “a process cannot be used ‘within’ the United States as required by section 271(a) unless each of the steps if performed within this country.” 418 F.3d 1282, 1318 (Fed. Cir. 2005)(en banc)(emphasis added). In contrast, the Court also held that “use of a claimed system under section 271(a) is the place at which the system as a whole is put into service, i.e., the place where control of the system is exercised and beneficial use of the system obtained.” Id. at 1317 (emphasis added). Unlike the method claim, for the system claim, the Federal Circuit upheld the finding of infringement even though one component of the claimed system was not present in the United States.

Conclusion

Whether the Supreme Court limits or expands the scope of patentable subject matter in Bilsky, it is apparent that the scope of method claims have already been limited. For those who thought (or just hoped) that method claims were the next best thing since means-plus-function claims…well, just like with means-plus-function claims, this was a good theory put to rest by subsequent case law. Its now time to adapt again.


Common Sense Practice Note: Things that today are considered "conventional wisdom" may not always have been considered "conventional" in the past, and may not always be considered "wisdom" in the future. For patent practitioners, the best strategy remains timeless - keep applying for claims of varying format, varying subject matter and varying scope, since one never knows what tomorrow may bring.

The 5 W’s (and How) – Not Just for Journalism Anymore

The Federal Circuit Heightens the Pleading Requirement for Inequitable Conduct

Sometime during grade school we learned that good journalistic writing needed to address “the five Ws”- who, what, when, where and why – and sometimes how. This is still true for good journalism. It is now also true for pleading the defense of inequitable conduct.

In Excergen Corp. v. Wal-Mart Stores, Inc. et al. the Federal Circuit recently addressed the requirements for pleading inequitable conduct under the heightened specificity requirements of Fed. R. Civ. P. 9(b). (2006-1491, 2007-1180, August 4, 2009, http://www.cafc.uscourts.gov/opinions/06-1491.pdf). The two elements of inequitable conduct are that (1) an actor within the duty of candor committed a material omission or made a materially false statement to the patent office, and (2) the omission or false statement was made with the specific intent to deceive the patent office. With respect to the first element, materiality, the Excergen court held “that in pleading inequitable conduct in patent cases, Rule 9(b) requires identification of the specific who, what, when, where and how of the material misrepresentation or omission committed before the PTO.” In addition, the Excergen court held that “a pleading of inequitable conduct under Rule 9(b), must include sufficient allegations of underlying facts from which a court may reasonably infer that a specific individual (1) knew of the withheld material information or of the falsity of the material misrepresentation , and (2) withheld or misrepresented this information with a specific intent to deceive the PTO” (emphasis added).

Under this heightened pleading standard, a general allegation against all individuals within the scope of the duty of candor, such as “Excergen, its agents and/or attorneys,” fails to address the “who” element with sufficient specificity and was deemed inadequate. In short, the court wants names (but also noted that these may be redacted from the public filing, if appropriate). For the “what” and “where” requirements, the pleading must now specifically identify not just a withheld reference, but those specific portions of the withheld reference that are considered material. General averments of “materiality” or that a reference is “not cumulative to the information already of record,” are insufficient. For materiality, the pleading now must “identify the particular claims limitations, or combination of claim limitations, that are supposedly absent from the information of record.” This, the court says, is “necessary to explain both ‘why’ the withheld information is material and not cumulative, and ‘how’ an examiner would have used this information in assessing the patentability of the claims.” Finally, the pleading must allege that the specific individual(s) identified “knew of [the] specific information that is alleged to be material [to the asserted patent] and then decided to deliberately withhold it from the relevant examiner.”

It is not news that inequitable conduct is a defense that requires pleading with specificity. Nonetheless, the heightened pleading requirements outlined in Excergen that provide a framework for meeting this requirement will be welcomed by many who view inequitable conduct as a defense that is raised too often, too early, and many times too vaguely. In practice, however, rather than significantly limiting the number of inequitable conduct allegations being made, Excergen is more likely to impact the timing and scope of these allegations. To address the five W’s (and “how”), defendants will require additional fact discovery before filing the amended pleading with the inequitable conduct defense. The allegations will still come, they will likely come later in the case and should be more thoroughly defined.

The Federal Circuit Reviews the Standard for Preliminary Injunctions in Design Patent Cases

Titan Tire Corporation et al. v. Case New Holland Inc., et al. 2008-1078

In Titan Tire, the Federal Circuit affirmed the trial court’s denial of a preliminary injunction (“PI”) in a design patent case. (www.cafc.uscourts.gov/opinions/08-1078.pdf) The opinion begins with a recitation of the four factors required to obtain a preliminary injunction which “are of longstanding and universal applicability.” That is, the movant “must establish [1] that he is likely to succeed on the merits, [2] that he is likely to suffer irreparable harm in the absence of preliminary relief, [3] that the balance of equities tips in his favor, and [4] that an injunction is in the public interest.” Although a movant must satisfy all four factors in every case, the focus of Titan Tire was on the first factor. More particularly, the opinion provides an in-depth discussion regarding the respective evidentiary and procedural burdens for establishing (or defeating) a showing that a patent holder “is likely to succeed on the merits” in the face of a validity challenge to the asserted patent. Although Titan Tire is a design patent case, the discussion with respect to the burdens encountered in a PI motion are equally applicable to utility cases as well.

The court begins its analysis with the truism that “the patentee seeking a preliminary injunction in a patent infringement suit must show that it will likely prove infringement, and that it will likely withstand challenges, if any, to the validity of the patent.” When an alleged infringer is challenging patent validity in its defense of a PI, “the burden is on the challenger to come forward with evidence of invalidity, just as it would be at trial.” (Well, almost “as it would be at trial.” As discussed below, the accused infringer does not need to present “clear and convincing” evidence of invalidity to defeat a motion for a preliminary injunction.) After the accused infringer presents some evidence sufficient “to persuade the trial court that the patent is invalid, at this stage it is the patentee, the movant, who must persuade the court that, despite the challenge presented to validity, the patentee nevertheless is likely to succeed at trial on the validity issue.” In this context, “[w]hile it is not the patentee’s burden to prove validity, the patentee must show that the alleged infringer’s defense lacks substantial merit.”

How much evidence does an accused infringer need to present for a successful invalidity challenge during a preliminary injunction hearing? Clearly, the accused infringer needs to come forward with enough evidence (something more than a “mere scintilla”) to persuade the court that its invalidity defense has “substantial merit.” The court unequivocally stated, however, that “the alleged infringer at the preliminary injunction stage does not need to prove invalidity by the ‘clear and convincing’ standard that will be imposed at trial on the merits.” Instead, this heightened evidentiary burden is merely “a consideration for the judge to take into account in assessing the challenger’s case at the preliminary injunction stage.”

Obviousness of Design Patents

After discussing the standard for determining whether an invalidity defense is sufficient to defeat a PI motion, the court continued with a discussion of the standard for determining invalidity of a design patent.

Obviousness for design patents, like utility patents, is governed by 35 U.S.C. 103. When combining multiple references for an obviousness defense, the inquiry is “whether one of ordinary skill would have combined the teachings of the prior art to create the same overall visual appearance as the claimed design.” As discussed in Titan Tire, this typically involves identifying a “primary reference;” that is “something in existence, the design characteristics of which are basically the same as the claimed design.” Then, “other ‘secondary’ references ‘may be used to modify it to create a design that has the same overall visual appearance as the claimed design.’” Finally, to properly combine the references, the "secondary references must be 'so related [to the primary reference] that the appearance of certain ornamental features in one would suggest the application of those features to the other.'" Citations omitted. After reviewing this standard, the court reviewed the prior art of record and affirmed the district court’s holding that the accused infringer's invalidity defense had sufficient merit to defeat the PI.

Although dicta, the court pointed out that current test for obviousness of design patents may have similar flaws as the “point of novelty” test for infringement that was eliminated by the Federal Circuit's en banc decision is Egyptian Goddess. The court did not, however, take the opportunity to take on this issue. Instead, it simply pointed out that gyptian Goddess expressly states that “it is not a test for determining invalidity, but is designed solely as a test of infringement.” After noting this limitation, the Titan Tire court simply warns that “it is not clear to what extent, if any, the doctrine applicable to obviousness should be modified to conform to the approach adopted by this court in Egyptian Goddess.”

Another interesting, but unanswered question, is the role of the Supreme Court’s decision in KSR in determining obviousness in the context of design patents. In particular, Titan Tire objected to the trial court’s reference to the passage in KSR that the “predictable use of prior art elements according to their established functions” would be indicative of obviousness since, it argued, design patents do not have functional elements. The Federal Circuit stated that “it is not obvious that the Supreme Court necessarily intended to exclude design patents from the reach of KSR,” but found that this question need not be resolved to dispose of the present case.

What are the take aways from Titan Tire?

• Preliminary injunctions represent extraordinary relief and are difficult to obtain. (Of course, we new that already). The Federal Circuit’s discussion in Titan Tire is likely to make it easier to defeat a PI motion based on a reasonably presented invalidity defense.
  
• The ordinary observer test of Egyptian Goddess does not have any bearing on the validity of design patents. The rational behind eliminating the “point of novelty” test, however, may continue to influence the validity inquiry in the future.
  
• We should expect to see KSR-based arguments raised more often in the context of design patents.

En Banc Decision Clarifies Scope of Product-By-Process Claims and Highlights Philosophical Divide in the Federal Circuit

En banc decisions from the Federal Circuit are rare. They serve to clarify the law, typically being invoked when conflicting precedent has been identified and needs to be reconciled. As such, en banc decisions are important. On May 18, 2009, the Federal Circuit issued its decision in Abbott Laboratories et al. v. Sandoz et al., 2007-1400, 1446 (http://www.cafc.uscourts.gov/opinions/07-1400.pdf). Most of the decision was panel-only. However, the Court, acting sua sponte, took on one issue en banc. That issue was the “proper interpretation of product-by-process claims.”

The Majority Holding

First, the law. The majority noted conflicting precedent from Federal Circuit panel decision regarding whether the process recitations in a product-by-process claims were properly construed as claim limitations. In other words, would an identical product, made by a different process, infringe a product-by-process claim? Making a long story short, the majority held that process recitations in a product-by-process claim are indeed claim limitations and if a product is made by a different process, there is no infringement.

Judge Newman’s Dissent

Judge Newman’s dissenting opinion, joined by J. Laurie and J. Mayer, is a 38 page dissertation taking issue with both the process used by the Federal Circuit in dealing with this issue en banc, and the substance of the majority’s holding.

Judge Newman is perhaps the Federal Circuit’s most consistent supporter of a strong patent system. Her opinions demonstrate a high level of respect both for patents and the patent bar. This dissent is fully consistent with these values.

First, the dissent is clearly unhappy with the perceived short-cutting of the en banc process in this case. For example, Judge Newman notes that the parties were not invited to brief or argue the en banc question and neither were amici. The dissenting opinion states that the Federal Circuit ran afoul of Fed. R. App. Proc. 34 and 35, as well as its own internal operating procedures, in taking on this issue without seeking such input. In Judge Newman’s view, those constituents likely to be effected by this change in the law should have been provided an opportunity to be heard.

Turning to the substance of the dissent, Judge Newman methodically dissects each case relied on by the majority and effectively points out why those cases fail to support the bright line test adopted by the majority. Rather, long standing authority, she points out, supports evaluating a product-by-process claim under a “rule of necessity” that traditionally allowed a patentee to claim the product by describing the process of manufacture when there was no known way of characterizing an otherwise novel product. Since both patentability and infringement were measured by the scope of the product, Judge Newman characterizes this approach as “pragmatic, fair, and just, for it attuned patent law and practice to the realities of invention.”

Practical Impact

From a practical standpoint, this decision will have limited impact since the use of product-by-process claims tend to be rare. (Indeed, its not even clear that they were appropriate in the case before the court since there were other claims involved that claimed the product based on measurable properties, rather than the process steps used to make the product). Nonetheless, the majority holding seems to present yet another small, but measurable, erosion of patent rights that are now available to inventors.
