[enhanced version available to lexis.com subscribers]

OVERVIEW:  Patents describing use of thiopurine drugs to treat autoimmune diseases contained unpatentable subject matter since correlation between blood metabolite levels and drugs were known laws of nature, and steps of administering drugs, applying natural laws in treatment, and measuring metabolite levels lacked inventive concept in applying natural laws.

CORE TERMS:  patent, laws of nature, metabolite, patentable, doctor's, thiopurine, formula, natural laws, correlations, patient ...

 

2. Promega Corp. v. Life Techs. Corp., 2011-1263, UNITED STATES COURT OF APPEALS FOR THE FEDERAL CIRCUIT, 2012 U.S. App. LEXIS 6309, March 28, 2012, Decided [enhanced version available to lexis.com subscribers]

OVERVIEW:  Pursuant to 9 U.S.C.S. § 2, the district court properly compelled arbitration of a royalty dispute because the parties had a valid arbitration agreement that mandated arbitration of disputes pertaining to royalties. The agreement was written broadly and did not limit the disputes to which it applied.

CORE TERMS:  promega, technology, arbitration, discovery, patent--, arbitrate, genetic, arbitration provisions, compel arbitration, licensed ...

 

3. 3M Co. v. Avery Dennison Corp., 2011-1339, UNITED STATES COURT OF APPEALS FOR THE FEDERAL CIRCUIT, 2012 U.S. App. LEXIS 6172, March 26, 2012, Decided [enhanced version available to lexis.com subscribers]

OVERVIEW:  Manufacturer's allegations were sufficient to provide jurisdiction for declaratory judgment that manufacturer did not infringe owner's patents for retroreflective sheeting, since owner effectively charged infringement by stating that manufacturer's products may infringe patents, offering license, and refusing to grant covenant not to sue.

CORE TERMS:  patent, declaratory judgment action, patentee's, infringement, declaratory judgment, charts, sheeting, patent rights, retroreflective, deadline ...

 

4. Ergo Licensing, LLC v. CareFusion 303, Inc., 2011-1229, UNITED STATES COURT OF APPEALS FOR THE FEDERAL CIRCUIT, 2012 U.S. App. LEXIS 6171, March 26, 2012, Decided [enhanced version available to lexis.com subscribers]

OVERVIEW:  With respect to a patent describing a medical infusion system, the district court correctly determined that the "control means" terms, means-plus-function language governed by 35 U.S.C.S. § 112, para. 6, were indefinite because they failed to disclose corresponding structure.

CORE TERMS:  specification, fluid, control device, control means, patent, metering, adjusting, invention, corresponding, disclosure ...

 

5. Marine Polymer Techs., Inc. v. HemCon, Inc., 2010-1548, UNITED STATES COURT OF APPEALS FOR THE FEDERAL CIRCUIT, 2012 U.S. App. LEXIS 5567, March 15, 2012, Decided,  As Amended March 17, 2012. [enhanced version available to lexis.com subscribers]

OVERVIEW:  Plain directive of 35 U.S.C.S. § 307(b) did not permit alleged infringer to invoke intervening rights against claims that the PTO confirmed on reexamination to be patentable as originally issued. The statute provided for intervening rights following reexamination only as to "amended or new" claims. The asserted claims of the patent were neither.

CORE TERMS:  intervening rights, reexamination, specification, reactivity, patent, biocompatible, polymer, biocompatibility, invention, biological ...

 

6. Aspex Eyewear, Inc. v. Marchon Eyewear, Inc., 2011-1147, UNITED STATES COURT OF APPEALS FOR THE FEDERAL CIRCUIT, 2012 U.S. App. LEXIS 5371, March 14, 2012, Decided [enhanced version available to lexis.com subscribers]

OVERVIEW:  District court erred when it found that a settlement agreement a patent owner entered with a competitor in an earlier action barred claims the owner filed against the competitor in a later action which alleged that new eyewear the competitor sold infringed U.S. Patent No. RE37,545. The doctrine of res judicata did not bar the owner's claims.

CORE TERMS:  frame, auxiliary, magnetic, res judicata, infringement, arm, spectacle, reexamination, patent, eyeglass ...

 

7. Zoltek Corp. v. United States, 2009-5135, UNITED STATES COURT OF APPEALS FOR THE FEDERAL CIRCUIT, 2012 U.S. App. LEXIS 5361, March 14, 2012, Decided [enhanced version available to lexis.com subscribers]

OVERVIEW:  Court of appeals vacated its decision in Zoltek Corp. v. United States, which limited the scope of 28 U.S.C.S. § 1498(a) to direct infringement under 35 U.S.C.S. § 271(a), because that decision misinterpreted § 1498 and was inconsistent with 35 U.S.C.S. §§ 154 and 271 and 19 U.S.C.S. § 1337.

CORE TERMS:  infringement, patent, manufacture, contractor, invention, patented process, foreign country, license, sovereign immunity, importation ...

OVERVIEW:  Where district court's determination of non-infringement under 35 U.S.C.S. § 271 was based in part on the erroneous claim construction of the term "registration server," the judgment was reversed in part and remanded. Inventors' alleged narrowing of scope in the prosecution history was not so clear and unmistakable as to warrant estoppel.

CORE TERMS:  server, registration, architecture, managed, specification, summary judgment, non-infringement, user, disavowal, invention ...

 

9. In re Staats, 2010-1443, UNITED STATES COURT OF APPEALS FOR THE FEDERAL CIRCUIT, 2012 U.S. App. LEXIS 4524; 101 U.S.P.Q.2D (BNA) 1930, March 5, 2012, Decided [enhanced version available to lexis.com subscribers]

OVERVIEW:  After a broadening reissue application had been filed within two year statutory period, an applicant was "not barred from making further broadening changes" after the two year period in the course of the prosecution of the reissue application. Rejection of claims as filed outside the 35 U.S.C.S. § 251 two-year statutory limitation was reversed.

CORE TERMS:  reissue, broadening, patent, embodiment, broadened, isochronous, original patent, linked, buffers', legislative history ...

 

10. MySpace, Inc. v. Graphon Corp., 2011-1149, UNITED STATES COURT OF APPEALS FOR THE FEDERAL CIRCUIT, 2012 U.S. App. LEXIS 4375; 101 U.S.P.Q.2D (BNA) 1873, March 2, 2012, Decided [enhanced version available to lexis.com subscribers]

OVERVIEW:  Patents relating to the ability to create, modify, and store database records over a computer network were invalid as anticipated or obvious based on prior art, since the term "database" was properly construed to include both hierarchical and relational data organization systems and thus the patents were not limited to hierarchical systems.

CORE TERMS:  patent, database, invention, user, subject matter, summary judgment, invalidity, relational, abstract ideas, stored ...
