Prosecution Group Luncheon Patents June, 2011
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—Inre 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
