Patent Infringement Litigation as a Double-Edged Sword: Invalidated Patents and Inequitable Conduct
| December 6, 2013
The Ohio Willow Wood Company (OWW) v. ALPS South LLC. (Alps)
Decided November 15, 2013
Before Dyk (Circuit Judge), Bryson (Circuit Judge) and Reyna (Circuit Judge). Opinion by Reyna.
Keywords: collateral estoppel, obviousness, inequitable conduct, reexamination, and rule of reason.
Summary:
OWW initiated a suit against Alps for patent infringement. After a long legal battle including two ex parte reexaminations, two District Court proceedings, and two CAFC appeals, OWW lost two patents and was charged with inequitable conduct.
Details:
OWW is the owner of US Patent No. 5,830,237 (the ‘237 patent), entitled “Gel and Cushioning Devices,” filed on March 5, 1996. The ‘237 patent disclosed cushioning devices designed to cover the residual stumps of amputated limbs, acting as a shape-conforming buffer, as illustrated below, to make the use of attached prostheses more comfortable. The primary invention was a cushion liner comprising a fabric covering in the shape of a tube sock coated on only one side with mineral oil-based polymeric gels.
On December 27, 2004, OWW filed its complaint against Alps for infringement of the ‘237 patent. After the District Court issued its Claim Construction order in the proceedings, Alps filed its first request for an ex parte reexamination of the ‘237 patent. The District Court stayed the litigation for the duration of reexamination proceedings, pending resolution of the validity of the disputed patent.

Election of species in case where there is no generic claim amounts to a “restriction” for applying safe harbor provision of 35 U.S.C. §121

St. Jude Medical, Inc. v. Access Closure, Inc.
September 11, 2013
Panel: Lourie, Plager and Wallach. Opinion by Plager. Concurring opinion by Lourie.
Summary:
St Jude Medical, Inc. asserts two sets of patents against Access Closure, Inc. (ACI). The patents claim methods and devices for sealing a “vascular puncture” into a vein or artery made during a medical procedure.
Claims 7, 8 and 9 of the Janzen patent are invalid for double patenting over the claims of a copending “sibling” application because claims 7, 8 and 9 are directed to an invention identified as Group II in a restriction requirement, further limited to species C, and the claims in the sibling patent are directed to a Group II invention but without any limitation to species. The safe harbor provision of 35 U.S.C. §121 does not apply because the claims of the Janzen patent are not patentably distinct from the claims of the sibling patent, and the patents do not maintain the “consonance” created by the original restriction requirement and requirement for election of species.
The claims of the two Fowler patents asserted by St Jude Medical are not obvious over a combination of two cited references because the references teach alternative methods (inserting a balloon or inserting a gelfoam stick) for achieving hemostasis, whereas the claims in the Fowler patents use a balloon for another purpose, i.e., to help position a plug and prevent it from entering a blood vessel.

Predictably Divided CAFC Panel Finds Computer System Claims Not Patent-Eligible
| September 17, 2013
Accenture Global Services, GMBH v. Guidewire Software, Inc. September 5, 2013 Panel: Lourie (author), Reyna, Rader (dissent) Summary:Not surprisingly, the decision of the latest Federal Circuit case on software patent eligibility can be predicted based on the makeup of the CAFC panel. Judge Lourie, joined by Judge Reyna, issued the majority opinion that the system claims were invalid. The Court followed the analysis for determining patent eligibility from CLS Bank, 717 F.3d 1269 (Fed. Cir. 2013) and affirmed the district court’s finding that the system claims of U.S. Patent No. 7,013,284 (“the ‘284 patent”) were ineligible. Judge Rader dissented.

Inventorship disputes raise difficult issues; involvement of State universities adds layers of complexity
| September 6, 2013
University of Utah v. Max-Planck-Gesellschaft
August 19, 2013
Panel: Moore, Reyna and Wallach. Opinion by Reyna. Dissent by Moore.
Summary:
This case started with the University of Utah suing the University of Massachussetts and others to obtain correction of inventorship in a group of patents co-owned by UMass and the other defendants. But the main issues in this appeal relate to the status of the plaintiff UUtah and initial co-defendant UMass as State entities.
To overcome UMass’ sovereign immunity defense (a State can be sued by another State only in the Supreme Court under Article III of the Constitution), UUtah amended its complaint to name individual UMass officials, instead of UMass itself.
The District Court held that the lawsuit could proceed, and the Federal Circuit affirms on the grounds that (1) UMass is not a “real party of interest” because deciding inventorship does not involve a core state interest, and (2) UMass is not an “indispensable party” because the officials can adequately represent the interest of UMass as co-owner of the patents.

Incorporation by reference by its entirety without further relevant citation to specific contents is insufficient to provide intrinsic record to trump the disclaimer in the specification

SkinMedica, Inc. v. Histogen Inc. et al.
August 23, 2013
Panel: Rader, Clevenger, Prost. Opinion by Prost. Dissent by Rader.
Summary:
SkinMedica owns the ’494 patent. It filed a patent infringement suit against Histogen. During the prosecution, the inventors limited their claimed inventions to pharmaceutical compositions comprising cell culture medium conditioned by animal cells cultured in three-dimensions. The issue is whether the claimed term, “culturing … cells in three-dimensions,” covers the use of beads. The ordinary meaning of the claimed term, “culturing … cells in three-dimensions” would cover the use of beads. The court found that the inventors expressly defined the use of beads as culturing in two-dimensions. Also, the inventors avoided anticipatory prior art during prosecution by asserting that the conditioned medium produced by two-dimensional cultures was inferior and chemically distinct from the conditioned medium produced by three dimensional cultures. SkinMedica also argued that the ’494 specification incorporates Doyle by reference, which explains the use of beads. However, the court rejected this argument since specific reference to the relevant discussion is not made in the intrinsic record, which does not trump the disclaimer in the specification.
SkinMedica は494特許を所有しており、Histogen社を特許侵害で訴えた。494特許の審査段階において、出願人はクレーム発明を補正し、3次元培養に限定し た。争点は、クレーム発明がビーズの使用を含むかどうかである。クレーム用語である「細胞を3次元で培養する」の通常の意味は、ビーズの使用を含む。しか しながら、裁判所は、内部証拠から判断して、発明者が、ビーズの使用は2次元培養であることを明確に定義したと判断した。また、発明者は審査段階において 新規性拒絶をクリアするために2次元培養で製造した調整媒体は劣っており、3次元媒体で製造した調整媒体と化学的に区別できることを主張した、と判断し た。また、494特許は、ビーズの使用を説明した文献（Doyle）を明細書に引用していたが（incorporation by reference）、関連箇所を示す説明が何もないとして、SkinMedicaの主張を退けた。
Instruction from PTO on Software Composition Claims

Ex parte Mewherter, 2012-007962 (PTAB, 2013)
The Patent Office rarely designates decisions of the Patent Trial and Appeal Board as being “precedential,” but when it does, practitioners take note. The Patent Office’s designation last week of Ex parte Mewherter, 2012-007692 as falling in that category will be of particular interest to those handling software patent applications.

Did the CAFC Extrapolate From the Teachings of the References to Reach the Conclusion of Obviousness?
| August 12, 2013
In re Adler
July 18, 2013
Panel: Prost, Reyna and Wallach. Opinion by Wallach
Summary
The Examiner rejected all of the pending claims under 35 U.S.C. §103 as obvious over several prior art references, including International Patent Publication WO 00/22975 (“Meron”) in view of Masaru Hirata et al., Study of New Prognostic Factors of Esophageal Variceal Rupture By Use of Image Processing With a Video Endoscope, 116 Surgery 8–16 (1994) (“Hirata”).
The Board of Patent Appeals and Interferences (“the Board”) affirmed the Examiner’s rejection of all pending claims of U.S. Patent Application No. 10/097,096 (the ‘096 application) under 35 U.S.C. §103 as being obvious over a combination of prior art references. Adler appealed the Board’s decision to the Court of Appeals for the Federal Circuit (CAFC). The CAFC affirms holding that the Board did not err in rejecting the pending claims as obvious and did not rely on new grounds for rejection.

Improper NDA Defeats Trade Secrets and Overly Broad Patent Claims are Invalid

Convolve v. Compaq Computer
July 1, 2013
Panel: Rader, Dyk and O’Malley. Opinion by O’Malley
Summary
Convolve, Inc. (“Convolve”) and Massachusetts Institute of Technology (“MIT”) appeal the decision of the U.S. District Court for the Southern District of New York (“District Court”) granting summary judgment in favor of Compaq Computer Corp. (“Compaq”), Seagate Technology LLC. and Seagate Technology, Inc. (“Seagate”).
Convolve and MIT sued Compaq and Seagate in July 2000 for breach of contract; misappropriation of trade secrets listed in Amended Trade Secret Identification (ATSI); direct patent infringement; and inducement of patent infringement along with other complaints such as fraud; violation of California Business and Professions Code §17200 (“CA Unfair Competition”), etc.
In May 2006, the District Court disposed of all other charges from the suit except the breach of contract, misappropriation of trade secrets and patent infringement charges. The District Court later granted summary judgment in favor of Compaq and Seagate and dismissed the remaining charges. With regard to the trade secret charges, the District Court found that:
(1) some of Convolve’s trade secrets (ATSI 1B, 2A, 2C, 2E, and 3B-D) were covered under a Non-Disclosure Agreement (NDA), which Convolve failed to properly preserve according to the NDA procedures;
(2) some of Convolve’s trade secrets (ATSI 2A, 6B, and 7A) were public known or common knowledge in the industry, which were not entitled to protection;
(3) some of Convolve’s trade secrets were never used by the defendants (ATSI 2F and 7E); and
(4) because New York law does not extend trade secret protection to marketing concepts, some of the trade secrets alleged by Convolve are not recognized by the District Court.
With regard to the patent infringement charges, the District Court found that:
(1) out of the four models of products alleged by Convolve as infringing Patent’473, none read on the claims of the patent;
(2) Patent’635 was found invalid for being non-enabling based on the inventor’s testimony; and
(3) since no direct infringement was found, the claim for inducement of patent infringement must fail.
Taking all inference in favor of Convolve, the CAFC affirmed all counts of summary judgment with regard to the trade secret allegations, as well as the invalidity of Patent’635, but reversed the non-infringement decision about Patent’473.
Convolve （原告）与Compaq， Seagate（康柏电脑和希捷数码，被告）就原告开发的一些硬盘技术进行技术合作谈判，双方就谈判涉及内容签订了保密协议。但原告在向被告透露相关技术时没有严格按保密协定约定的程序处理涉密内容。后来改谈判未能达成一致，原告诉被告在谈判涉及的保密内容上侵犯商业机密及在另一些技术问题上专利侵权。一审结果，联邦区域法院裁定原告败诉。
上述法院均认定，尽管侵犯商业机密属于一个侵权法的范畴，然而在已签订合同中原被告双方均已同意以合同条款规定商业机密的范畴，故侵权法默认的商业机密标准不适用。因原告在履行保密协议过程中未遵循商定的处理程序，原告在此案中已丧失对该商业机密的索赔权。
另外， 关于专利侵权案，原告的专利在当年提出申请时对该发明的描述超过了发明人的当时可以实施实际该发明的范畴，故该专利被认定未能适当描述其实施方法因而无效。上述法院部分维持一审法院的判决。
