RECENT CASE HIGHLIGHTS
    • This precedential inducement, DOE, and estoppel decision (whew!) considers a method for "trying to implant an artificial heart valve to replace a defective valve, that furnishes a do-over opportunity to the installer to get the positioning right." Basically, infringement by inducement was found below, based on direct infringement by DOE, despite evidence of estoppel in the prosecution history. Defendant here argues "that Colibri’s cancelling during prosecution of then-claim 39— while retaining then-claim 34 (which issued as claim 1)— “precludes Colibri from asserting that, under the [doctrine of equivalents], partial deployment and recovery of the valve is performed by retracting the sheath.”" CAFC agrees, and so here reverses. Below, the DCT believed "that the asserted equivalent (i.e., the implantation method of Medtronic’s Evolut system) differs distinctly from what was recited in cancelled claim 39" as "claim 39 did not require pushing the inner member—only retracting the moveable sheath." Alas, plaintiff also repeatedly asserted that PHOSITA "would understand that pushing necessarily accompanies retracting." Similarly, "Colibri’s cancelling of claim 39 in favor of pursuing limitations that already appeared in retained claim 34 (issued claim 1) was a narrowing amendment giving rise to prosecution history estoppel." Relevant to this opinion's precedential status, CAFC is clarifying that the narrowing required for estoppel can occur in this indirect manner ("[T]he required narrowing is not a purely formal matter of altering a single claim’s terms; it can exist, and we conclude here does exist, as a substantive matter based on cancelling a closely related claim involving such intertwined terminology that cancelling one claim necessarily communicated that the scope of the other claim had narrowed . . . Governing law precludes making formalities determinative, to the exclusion of substantive relationships that would be understood by relevant readers . . . we do not address each claim in isolation", emphasis added).
    • In this precedential design patent decision involving an "Enlarged Over-Garment with an Elevated Marsupial Pocket" (think, "super-sized" hoodie), CAFC finds prosecution history disclaimer and "that Top Brand was entitled to JMOL of noninfringement of the design patent because the accused infringing design was within the scope of the subject matter surrendered during prosecution." Initially, CAFC sets aside argument that the claim construction challenge was waived, since it wasn't raised again after trial ("[A] party need not reiterate its preferred claim construction that it argued during earlier claim construction proceedings if the position has been rejected"). As for the disclaimer, there's already precedent in the design space for disclaimer (e.g., in Pacific Coast, "[t]he examiner issued a restriction requirement, and the applicant responded by “cancelling figures associated with all but one of the patentably distinct groups . . . We held that, by doing so, “the applicant narrowed the scope of his original application, and surrendered subject matter.”"). Here, argument also sufficed to effect the disclaimer ("Cozy Comfort argued the overall ornamental appearances of the claimed design and the prior art White design were distinguishable under the ordinary observer test. Cozy Comfort explained how its design differed from White by focusing on specific distinguishing features such as the shape and placement of the marsupial pocket and shape of the bottom hem line. In making these arguments, Cozy Comfort surrendered the identified features as supporting a finding of overall similarity."). Specifically, applicant celebrated relations between the marsupial pocket and the arm holes over the prior art during prosecution. Under the Egyptian Goddess analysis, CAFC finds that disclaimer should have resulted in a JMOL for noninfringement and so reverses after briefly considering trademark claims, for which it reaches the same conclusion based upon the evidentiary record ("Cozy Comfort cannot remove the descriptive term “comfy” from the public domain without a showing of secondary meaning, which it has not made").
    • CAFC precedentially affirms the Board's obviousness finding in this IPR for some claims and reverses its nonobviousness finding for other of the claims, each directed to balloon angioplasty. CAFC again reiterates that while admitted prior art (AAPA) cannot, in itself, form the basis for a petition, it can be considered in the IPR analysis ("We have explained that “[a]lthough the prior art that can be considered in [IPRs] is limited to patents and printed publications, it does not follow that we ignore the skilled artisan’s knowledge when determining whether it would have been obvious to modify the prior art” . . . Our decisions in Qualcomm I and Qualcomm II accordingly require that only patents and printed publications form the basis of an IPR . . . However, AAPA can be important evidence of general background knowledge, and general knowledge can be used to supply a missing claim limitation . . . This case is quite different from Qualcomm II, where the petitioner expressly labeled AAPA as the “basis” for its challenge"). As for the cross-appeal, CAFC first acknowledges standing ("Although a company’s representations about its intent to protect its intellectual property do not always give rise to a substantial likelihood of litigation, Shockwave’s President’s broad claims reflect the company’s expansive view of claim 5 as reading broadly on IVL technology."), before finding the Board's analysis too limited ("The problem with the Board’s analysis is that it was predicated on its finding that Uchiyama alone did not disclose that the electrodes were positioned “adjacent to and outside of the guidewire lumen,” since the argument raised by CSI before the Board was based on the combined teachings of Levy as modified by an over-the-wire catheter balloon and Uchiyama. The standard for obviousness requires consideration of the prior art combination taken as a whole."). Ergo, reversed and remanded as to the cross-appeal.
  • In Re WHITE - 2025-07-10
    • Brief affirmance that "YUCATAN SHRIMP" is descriptive ("[T]he public understands “Yucatan Shrimp” to refer to a dish that features shrimp prepared with a set of common ingredients associated with Mexican cuisine, such as hot peppers or sauce, citrus juice, and cilantro"). Further proof that you-ca-can't-yu-ca-tan. Proceed accordingly.
    • CAFC affirms IPR obviousness invalidity for claims directed "to heating, ventilation, and air conditioning (HVAC) systems." Owner makes three arguments based upon the Board's analysis, and a fourth asserting that the petition "did not disclose a sufficient obviousness theory for “detecting a manual change to the first automated setpoint” because Google relied on “general concepts” rather than a “particular example.”" CAFC resolves the first three with reference to the Board's factual findings, and the fourth in a similar manner, since the Board's analysis relied on the petition's assertion ("EcoFactor does not point out any particular deficiency in the Board’s conclusion that Ehlers and Wruck render this claim element obvious").
