Have You Included Specific Reference to Every Document in Your Priority Claim?
Incorporation by reference is not sufficient to satisfy specific reference to each prior-filed patent application to be entitled to an earlier priority date (Droplets, Inc. v. E*Trade Bank (887 F.3d 1309 (2018)).

How the PTAB Reviews Software Inventions Under the 2019 Revised Subject Matter Eligibility Guidance

PTABWatch Takeaway: The United States Patent and Trademark Office (USPTO)’s 2019 Revised Patent Subject Matter Eligibility Guidance provides a useful, and effective, tool for demonstrating patent eligibility of software-related inventions. While the 2019 Guidance acts as persuasive authority only, the PTAB has relied on the 2019 Guidance as a rubric in numerous cases to analyze, and find patent eligible, software-related inventions. Practitioners and inventors seeking to overcome, or avoid, patent eligibility issues under Section 101 would do well to draft or amend claims in view of the 2019 Guidance.

FC Affirms Obviousness Decision by Board Trigger of Time Bar

In Hamilton Beach Brands, Inc. v. F’real Foods, LLC, Appeal No. IPR2016-01107 (Fed. Cir. Nov. 16, 2018), the Federal Circuit affirmed the Patent Trial and Appeal Board’s final written decision in an IPR upholding the patentability of a patent claim under 35 U.S.C. § 103. Additionally, the court discussed but did not determine whether improper standing at the time of filing a complaint might impact the application of the one-year time bar under 35 U.S.C. §315(b). The decision provides a good opportunity for practitioners to brush up on the fundamentals governing obviousness determinations and suggests that the case law surrounding the one-year time-bar under §315(c) may still evolve.

Trade Show Publication Dooms Patent in IPR Appeal Despite Contrary Decision in ITC Appeal
Inter partes review not only provides a faster and cheaper way to challenge patent validity, but also expands the Patent Office’s ability to develop law on esoteric issues relating to prior art. The Federal Circuit’s decision Nobel Biocare Services AG v. Instradent USA, Inc. is another in a line of cases arising out of IPR proceedings dealing with the availability of conference and trade show materials as prior art. See, for example, PTABWatch posts here and here. Interestingly, the court affirmed the PTAB’s decision finding certain claims of the challenged patent anticipated by a trade show publication, whereas the court came to the opposite conclusion in a related ITC appeal based on the same publication.
