Patent Prosecution Lunch June 2011 Patent Prosecution Lunch June 2011 Presentation Transcript

  • Prosecution Group Luncheon June, 2011 Patents
  • Clear and Convincing Survives
    • Microsoft Corp. v. i4i Ltd. P’ship (US 2011)
    • §282 requires proof of invalidity defense by clear and convincing evidence (8-0 decision)
    • Validity presumption a fixture of common law when §282 enacted
    • “ [H]eavy burden of persuasion,” with proof of the defense by clear and convincing evidence
    • Common-law term in statute comes with its common-law meaning
    • Ergo, no conclusion that standard changed simply because §282 fails to reiterate it expressly
  • Clear and Convincing Survives
    • Presumption not weaker for information not considered during prosecution
    • “ [N]ew evidence” of invalidity likely carries more weight than evidence considered by PTO
    • “ [B]urden to persuade the jury of its invalidity defense by clear and convincing evidence may be easier to sustain” if “PTO did not have all material facts before it”
    • Jury instructions will handle effect of “new evidence”
  • Analogous Art— In re Klein (FC 2011)
    • FC: 5 cited references not “analogous art,” excluded from nonobviousness analysis 
    • Recall: reference is “analogous” if either
      • in the same field of endeavor as the invention or
      • “ reasonably pertinent” to inventor’s problem
    • “ Same field of endeavor” not addressed; rejections were based only on the “reasonably pertinent” test
  • In re Klein
    • Device for measuring/mixing sugar
    • and water for bird feeders
    • PTO: obvious over references com-
    • bined with known ratios for species
    •  
    • Problem: “making a nectar feeder with a movable divider to prepare different ratios of sugar and water for different animals”  
      • Solid item separators were not pertinent: “none . . . shows a partitioned container that is adapted to receive water or contain it long enough”
      • References for dividing liquids that would later be mixed not pertinent because they did not address multiple ratio problem and did not have movable dividers
  • In re Klein
    • Defining a narrow purpose for the invention, versus risk of limiting claim scope
    • Is a reference in a separate field will non-analogous unless pertinent to the entire problem?
    •   
    • FC did not cite KSR ; PTO viewed  KSR as expanding scope of analogous art (MPEP 2141.01(a)).
    •  
    • Commentator: Klein approach to analogous art may make obviousness analysis less subjective
    • h/t to PatentlyO.com
  • Therasense
    • Curtails application of inequitable conduct
    • Heightened intent and materiality standards
    • Egregious/fraudulent conduct still sanctionable
    • USPTO “carefully studying” the decision; “expects to soon issue guidance to applicants related to the prior art and information they must disclose”
  • Stanford v. Roche (US 2011)
    • Federally-funded contractor does not necessarily own patent rights to inventions resulting from funded projects (7-2 decision)
    • Stanford argued that rights vest automatically vest under the Bayh-Dole Act
    • Court: US patent rights have initially vested in “the inventor”; language of Bayh-Dole Act does nothing to change that
