The Patent Eligible Subject Matter Debate Continues

No question in patent law in recent times has been quite as vexing as the scope of patent eligible subject matter, especially as it relates to computer-implemented methods.  The Supreme Court has addressed the issue twice in three years in Bilski and Prometheus Labs, and we still seem no closer to understanding what makes an invention “patent elibible” under 35 U.S.C. 101.   The debate keeps on rolling along with the Federal Circuit's recent decision in CLS Bank Int’l  v. Alice Corporation, 2011-1301.

The claims at issue in CLS were found in three patents that each “cover a computerized trading platform for exchanging obligations in which a trusted third party settles obligations between a first and second party so as to eliminate ‘settlement risk..’”  Opinion at 2.  The claims at issue cover three different statutory classes, with method claims, system claims and article of manufacture claims directed to computer instructions stored on computer readable media.  The district court analyzed the claims in each class separately and found all claims invalid as not defining patent eligible subject matter under 35 U.S.C. 101.

In reversing the district court, the majority provided a lengthy discussion on the history of patent eligibility cases, especially addressing the “abstract idea” and “law of nature” exceptions to patent eligibility.  Opinion 11-21.  (Since the first paragraph of the ten page analysis includes the quote 'Congress intended statutory subject matter to "include anything under the sun that is made by man,"' [citations omitted] you quickly get a sense where the majority is headed).  At the end of its 10 page discussion, the majority sets forth a somewhat remarkable holding: “this court holds that when -- after taking all of the claim recitations into consideration — it is not manifestly evident that claim is directed to a patent ineligible abstract idea, that claim must not be deemed for that reason to be inadequate  under 101.”  Opinion at 20.  I for one, am lost by this statement.  A patent is presumed valid and a party seeking to invalidate a patent claim must do so by clear and convincing evidence.  It was my impression that this same standard applies to defenses under 35 U.S.C. 101.  I am not sure what “manifestly evident” is, but it sounds like a higher burden than clear and convincing evidence.  Perhaps, the defendant’s new burden on this issue is to prove by clear and convincing evidence that it is “manifestly evident that [an asserted] claim is directed to a patent ineligible abstract idea” in order to prevail on this issue?

The case includes a spirited dissent by J. Prost (with barbs and jabs laced throughout both the majority and dissenting opinions) that argues that “[t]he majority has failed to follow the Supreme Court’s instructions—not just in its holding, but more importantly in its approach.”  Dissent at 3.

Much more could be said about this 27 page opinion and 11 page dissent.  But, since the petition for rehearing en banc is likely already being drafted (and in my opinion will likely be granted), we might as well wait for the en banc opinion to delve deeper into this case.  

Federal Circuit Rejects Computer Readable Media Claims under Section 101

The ebb and flow regarding the scope of patentable subject matter for computer-related inventions continues this week with the Federal Circuits decision in Cybersource Corp. v. Retail Decisions, Inc.

In Cybersource, two claims of U.S. Patent No. 6,029,154 (“the ‘154 patent”) were invalidated by the district court under 35 U.S.C. § 101 for failure to recite patent-eligible subject matter.  One of the claims, Claim 3 was directed to a “method for verifying the validity of a credit card transaction” and recited three steps, including “obtaining information…”, “constructing a map of credit card numbers…,” and “utilizing the map…to determine if the credit card transaction is valid.”   Claim 2 was directed to “computer readable medium containing programming instructions” and recited “execution of the program instructions by one or more processors of a computer system” in the body of the claim.  The Federal Circuit affirmed. 

The decision with respect to the naked method claim (claim 3) is not too controversial.  The outcome with respect to Claim 2, however, represents a significant shift in the patent-eligible subject matter landscape.  Why, you ask?  Because for the last 15 years, patent practitioners in the computer arts have relied on In re Beauregard, 53 F.3d 1583 (Fed. Cir. 1995) for the proposition that claims drawn to “computer readable media” were patent-eligible articles of manufacture, not methods subject to the vagaries of Section 101. (“The Commissioner now states ‘that computer programs embodied in a tangible medium, such as floppy diskettes, are patentable subject matter under 35 U.S.C. § 101 and must be examined under 35 U.S.C. §§ 102 and 103.’)  (Note - there was no actual holding from the Federal Circuit in In re Beauregard, simply a remand. Since the Commissioner ultimately agreed with Beauregard’s position, there was no longer a case or controversy and thus no jurisdiction before the Federal Circuit.) The Federal Circuit has now dispelled this long-held reliance: 

Cybersource contends that, by definition, a tangible, man-made article of manufacture such as a ‘computer readable medium containing program instructions’ cannot possibly fall within any of ht three patent-eligibility exceptions the Supreme Court has recognized for ‘laws of nature, physical phenomena, [or] abstract ideas.” [citation omitted] We disagree.  Opinion at 16.

With those two words, the validity of claims in thousands of issued patents to computer-related inventions  are now in doubt. 

One line from this opinion that I find somewhat disturbing is that “[r]egardless of what statutory category (‘process, machine, manufacture, or composition of matter’ 35 U.S.C. § 101) a claims language is crafted to literally invoke, we look to the underlying invention for patent-eligibility purposes.”  In every other context we need to look at the claim language, all of the claim language, in order to define the “invention.”  Under the Cybersource analysis, courts may now ignore express limitations in the claim (such as “computer readable media” or “one or more processors”) to determine an “underlying invention” that is broader than what is actually claimed in order to invoke Section 101.  Creating a double standard for the Section 101 analysis just doesn’t feel right.

Very little is certain about the scope of patent-eligible subject matter for computer-related inventions in view of the Cybersource decision except this:  we have not seen the end of this issue.  My bet is that en banc review is in our near future.

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.
