Bilski V. Kappos: Are Business Methods Still Patentable?
July 06, 2010
By Jay Moldovanyi, Joe Dreher and Eric Highman
On June 28, 2010, the United States Supreme Court finally decided the long-awaited Bilski case.
The Bilski claims pertained to a method by which buyers and sellers of commodities in the energy market can protect, or hedge, against the risk of price changes. The Patent Examiner concluded that the claims were not patentable under Section 101 of the Patent Act. Section 101 states that any new and useful process, machine, manufacture, or composition of matter, is patentable. Here, the focus was on the definition of “process,” and the Examiner concluded that the claims were to an abstract idea, which was not a process. The Board of Patent Appeals and Interferences upheld the Examiner. The Federal Circuit likewise found the Bilski patent application ineligible for patent protection. However, the Federal Circuit employed a newly articulated “machine or transformation” test to hold the Bilski claims unpatentable and said this was the only test for eligibility of process claims. In order to pass this test for patentability, a process must either be tied to a special purpose machine or apparatus, not just a general purpose computer, or the process or method must transform an article into “a different state or thing.”
The Supreme Court held that Bilski’s concept of hedging described in the claims is an unpatentable abstract idea just like the algorithms which were at issue in earlier Supreme Court decisions in Parker v. Flook, 437 U.S. 584 (1978) and Gottschalk v. Benson, 409 U.S. 63 (1972). The Court held that Mr. Bilski was trying to patent both the concept of hedging risk and the application of this concept to the energy markets.
The ruling was fragmented. In a 5-4 ruling, the Supreme Court rejected as overly rigid the Federal Circuit’s “machine or transformation” test as the sole test for determining whether a claimed process is patent eligible. The majority’s 16-page decision stated that “In disapproving an exclusive machine - or - transformation test, we by no means foreclose the Federal Circuit’s development of other limiting criteria that further the purposes of the Patent Act and are not inconsistent with its text.”
Justice Stevens, in a 47-page concurring opinion joined in by three other justices, stated that the Bilski claims were to a business method and all business methods should be held categorically unpatentable. Justice Breyer, in part 2 of his concurring opinion, in which Justice Scalia joined, stated that all the justices are in agreement on the following four points:
1. Section 101 of the Patent Act is broad, but not without limit.
2. The machine or transformation test is useful for identifying a patentable process.
3. The machine or transformation test is not the sole test for identifying patentable subject matter.
4. The “useful concrete and tangible result” test which the Federal Circuit developed in State Street Bank & Trust Co. v. Signature Financial Group, 149 F.3d 1368 (Fed. Cir. 1998) has never been endorsed by the Supreme Court as a test for determining whether the claims of a patent application contain patentable subject matter.
Thus, the Supreme Court opinion offers no dispositive rule for those tasked with determining whether a particular method or process claim is statutory under Section 101 of the Patent Act.
After the Bilski decision was issued, a notice to the Examiners at the Patent Office stated that:
Examiners should continue to examine patent applications for compliance with Section 101 using the existing guidance concerning the machine or transformation test as a tool for determining whether the claimed invention is a process under Section 101. If a claimed method meets the machine or transformation test, the method is likely patent eligible under Section 101 unless there is a clear indication that the method is directed to an abstract idea. If a claimed method does not meet the machine or transformation test, the Examiner should reject the claim under Section 101 unless there is a clear indication that the method is not directed to an abstract idea. If a claim is rejected under Section 101 on the basis that it is drawn to an abstract idea, the applicant then has the opportunity to explain why the claimed method is not drawn to an abstract idea.
While Bilski ultimately holds that business methods are not per se unpatentable, the practical effect of this decision may well be that patents on business methods will be much more difficult to obtain in the future.
Can the Same Word Have Different Meanings in Different Claims?
June 30, 2010
By Grant Steyer, Law Clerk
While not a recommended claim drafting procedure, it is possible to define the same word differently in different claims. It is, however, not possible to define a word differently within the same claim. The Federal Circuit recently addressed this issue in Haemonetics Corp. v. Baxter Healthcare Corp., 2010 U.S. App. LEXIS 11122 (Fed. Cir. 2010).
Haemonetics brought suit against Fenwal (Fenwal became an independent corporation from Baxter when Baxter divested its centrifugal therapies business) for patent infringement, alleging that a centrifugal system developed and sold by Fenwal infringed claim 16 of their U.S. Patent No. 6,705,983 (“the ‘983 patent”). Fenwal counterclaimed that claim 16 of the ‘983 patent was invalid for indefiniteness, lack of novelty, and obviousness. During trial, the district court was required to interpret claim 16, because “centrifugal unit” was defined differently in claim 16 than it was in claim 1 of the patent. In claim 1, “centrifugal unit” was defined as comprising only a vessel. Later in the patent, at the beginning of claim 16, “centrifugal unit” was identified as comprising a vessel and a plurality of tubes. However, at the end of claim 16, contradicting the definition given earlier in the same claim, “centrifugal unit” was used as if it comprised only a vessel. If the court found the use of “centrifugal unit” in claim 16 to be inconsistent, it was more likely that a jury would find the claim indefinite and invalid. See Id. at 12 (For a claim to be indefinite “one of ordinary skill in the relevant art could not discern the boundaries of the claim based on the claim language”). The district court did not find the use of “centrifugal unit” in claim 16 to be contradictory, but rather construed the later use of “centrifugal unit” in claim 16 to refer to the vessel only, despite centrifugal unit being defined earlier in the same claim as a vessel and plurality tubes.
On appeal, the Federal Circuit overruled the district court’s interpretation of the claim. The Federal Circuit found that claim 16 “unambiguously defines ‘centrifugal unit’ as ‘comprising’ two structural components” and that reading “centrifugal unit” later in the same claim to refer only to the vessel “ignores the antecedent basis for ‘the centrifugal unit’” as used in the claim. Id. at 9. Citing Federal Circuit precedent, the court found that “‘centrifugal unit’ has one meaning in claim 1 and another [meaning] in claim 16.” Id. at 10; See, Wilson Sporting Goods Co. v. Hillerich & Bradsby Co., 442 F.3d 1322 (Fed. Cir. 2006) (the Federal Circuit held that “gap” had two different meanings in two separate independent claims). Finding that “centrifugal unit” referred to a vessel and plurality of tubes in claim 16 and only a vessel in claim 1, the Federal Circuit held that the later use of “centrifugal unit” in claim 16 referred to a vessel and plurality of tubes. The court found the district court’s holding that the later use of “centrifugal unit” in claim 16 as only a vessel to be “nonsensical.” The court remanded the case back to the district court for a determination of whether claim 16 as so construed is invalid.
Redefining a previously defined term between multiple claims in a patent is allowable, but not recommended. As Haemonetics demonstrates, multiple definitions for a single word can lead to errors during the patent drafting process itself, and may well confuse the reviewing court.
When Are You Liable For False Marking?
June 30, 2010
By Kyle McMahon, Law Clerk
Displaying expired patent numbers on your products may lead to costly litigation requiring you to rebut the initial presumption that these markings were deceptive. “False marking” is defined in 35 U.S.C. § 292(a) as marking “in connection with any unpatented article, the word ‘patent’ or any word or number importing that the same is patented, for the purpose of deceiving the public . . . .” The act of false marking comes with a penalty of “not more than $ 500 for every such offense.” See 35 U.S.C. § 292(a).
Earlier, the Federal Circuit addressed the issue of what is meant by “every such offense” in Forest Group, Inc. v. Bon Tool Co., holding that penalties should be imposed on a per article basis. See 590 F.3d 1295, 1304 (Fed. Cir. 2009). Most recently, the Federal Circuit addressed the liability for false marking in Pequignot v. Solo Cup Co., No. 2009-1547, 2010 WL 2346649, (Fed. Cir. Jun. 10, 2010). In this case, Matthew A. Pequignot (“Pequignot”) appealed from a district court decision granting summary judgment to Solo Cup Co. (“Solo”) of no liability for false marking. See Pequignot v. Solo Cup Co., 646 F.Supp.2d 790 (E.D. Va. 2009). Over $10 trillion was at stake in this case because Solo had allegedly falsely marked over 21 billion articles (cup lids).
Solo owned U.S. Patent Re. 28,797 (issued May 4, 1976) and U.S. Patent No. 4,589,569 (issued May 20, 1986). Solo began marking the covered products with their respective patent numbers by adding these numbers to their mold cavities.
Solo’s U.S. Patent Re. 28,797 expired on June 8, 1988. In June 2000, Solo learned that it was still marking its products with an expired patent number. At this time, based on outside counsel’s advice, Solo developed a policy where the current mold cavities would be replaced with mold cavities without the expired patent marking when they needed to be replaced for wear or damage. Solo adopted this same policy when U.S. Patent No. 4,589,569 expired on October 24, 2003.
Pequignot brought a qui tam action (Pequignot would receive half of any penalty against Solo, with the remaining half being awarded to the United States) alleging that Solo knew that these patents had expired and falsely marked its products with the patent numbers for the purpose of deceiving the public. The Federal Circuit agreed with the District Court and Pequignot that “articles marked with expired patent numbers are falsely marked” and thus, Solo’s products were falsely marked. See Pequignot v. Solo Cup Co., 2010 WL 2346649 at *5. However, this did not, by itself, satisfy the requisite mental state of Solo for liability; Solo must have falsely marked products for the purpose of deceiving the public.
The Federal Circuit stated that the combination of a false statement and knowledge that the statement was false merely creates a rebuttable presumption of intent to deceive the public. See id. at *6. When the false markings at issue are expired patents that had previously covered the marked products, this presumption of intent to deceive is weaker. See id. at *7. Additionally, Solo referred to the advice of its counsel as evidence that the true intent of its policy was to reduce business costs and disruption and noted that it implemented and followed this policy to rebut this presumption. See id. Pequignot had not provided any credible contrary evidence. See id. at *8.
Thus, the Federal Circuit agreed with the District Court’s summary judgment holding in favor of Solo because the required intent to deceive the public with the false patent markings was not present. See id.
Be Specific In Your Specification
June 30, 2010
By DeMarcus Levy, Law Clerk
The filing date of a patent application can be critical in determining what prior art can be applied against its claims. In April 2010, Nintendo of America obtained a reversal of a U.S. District Court decision holding that certain Nintendo video game controllers infringed upon a patent, U.S. Patent 6,906,700 (“the ‘700 patent”), owned by Anascape. Anascape, Ltd. v. Nintendo of Am., Inc., 601 F.3d 1333, 1339 (Fed Cir. 2010). The district court held the Anascape ‘700 patent valid and infringed, and awarded damages of $21M. Anascape, Ltd. v. Ninendo of Am., Inc., No. 9:06-CV-158 (E.D.Tex. July 23, 2008). The pivotal issue was the filing date that Anascape’s ‘700 patent could rely on, as that would determine what prior art could be cited against the claims of the patent. Anascape sought to remove prior art in the form of Sony’s “DualShock” (patented in 1998) and “DualShock 2” (patented in 2000) video game controllers by claiming priority to its earlier patent, U.S. Patent 6,222,525 (“the ‘525 patent”), which was patented in 1996. The district court held that the ‘700 patent was substantially described by the ‘525 patent and was thus entitled to the filing date of the ‘525 patent.
To obtain the filing date of a parent patent, the claims of the child patent application must be so described in the parent patent “that one skilled in the art can clearly conclude that the inventor intended the [child] invention as of the [parent patent] filing date sought.” Lockwood v. American Airlines, Inc., 107 F.3d 1566, 1572 (Fed. Cir. 1997). In other words, for a child patent application to be entitled to use of the filing date of a parent patent it must be shown that the parent patent’s specification contained a sufficient description of the later-claimed subject matter of the child patent. Without such a showing, the child patent only receives its own filing date as it is “new matter” for which the parent patent does not give sufficient disclosure.
Here, Anascape asserted that the specification of the ‘525 patent described a controller having a single input member that operated in six degrees of freedom. In addition Anascape asserted that the specification of the ‘525 patent could also be construed to support claims for controllers having multiple input members that together operate in six degrees of freedom (6 DOF), as this was the subject matter described and claimed in the ‘700 patent. The district court noted that for the parent patent “[Anascape] clearly expected the inventions to be used with a single input member (such as a joystick) that moved in 6 DOF to control an image appearing to move in three dimensions.” Anascape, Ltd. v. Nintendo of Am., Inc., No. 9:06-CV-158 (E.D.Tex. July 23, 2008). The Federal Circuit conceded this, but held that the specification of the parent patent failed to explicitly disclose multiple input members that together operate in 6 DOF. The court noted, “A patentee is not deemed to disclaim every variant that it does not mention. However, neither is a patentee presumed to support variants that are not described.” Anascape, Ltd. v. Nintendo of Am., Inc., 601 F.3d 1333, 1339 (Fed. Cir. 2010) (referencing Amgen Inc. v. Hoechst Marion Roussel, Inc., 314 F.3d 1313, 1330 (Fed. Cir. 2003)). In short, the only claimed subject matter in a child patent application which is entitled to the filing date of a parent patent application is the information explicitly and understandably described in a parent patent and intended to apply to future inventions, such as those described in the child patent application.
Court Ruling Unleashes Flood of False Marking Lawsuits. Fay Sharpe Advises Clients to Take Proactive Steps.
March 30, 2010
In the past few weeks an attorney, Thomas Simonian, has filed more than 38 lawsuits against companies (such as Pfizer, Blistex, Ciba Vision, Hunter Fan, Kimberly-Clark, Mead Westvaco, Oreck, Fiskars, 3M, BP, Novaris, Merck, L'Oreal, Playtex, Abbott Laboratories, Allergan, Bausch and Lomb and Maybelline) claiming that the defendants falsely marked patent numbers on their products. The Patent Compliance Group, Inc., Hollander, Public Patent Foundation, Heathcote Holdings Corp., Inc., Brinkmeier, Perfection Product Management, LLC and Zojo Solutions Inc. have filed similar suits against a multitude of defendants.
It is not mandatory to list a patent number on a product covered by the claims of the patent. However, failure to mark your products with a patent means you are barred from obtaining damages for infringement that occurred prior to your informing an infringer of the existence of your patent.
All of the defendents in these cases mark patent numbers on their products. However, many of the patent numbers listed allegedly are expired, contain typographical errors directing the consumer to the wrong patent, or have a scope which does not cover the marked product. The plaintiffs also claim that the defendants' actions were intentional in an effort to "deceive the public and to gain a competitive advantage in the market." These suits have been filed as qui tam actions brought on behalf of the public whereby any private citizen can sue to recover the monetary penalty and retain for itself one half of the penalty awarded. Section 292 of the Patent Act provides that a person who falsely marks an unpatented article as being patented, where the false patent marking was done with intent to deceive the public, shall be fined not more than $500 for every such offense. "Offense" has recently been interpreted to mean every article sold.
Fay Sharpe LLP urges its clients to take proactive steps to avoid becoming embroiled in false marking litigation. Please contact us if you need assistance in performing a review of products and/or literature listing patent numbers.
