The Patent and Trademark Office (PTO) may reject a patent application on several different grounds.  One of those grounds is obviousness.  Under 35 U.S.C. § 103, if an invention is obvious to a person of ordinary skill in the art, then it is not patentable.

In determining whether an invention is obvious, the PTO compares the invention to the “prior art” – all similar inventions that are publicly available at the time the application is filed.  If the PTO rejects the invention as obvious, the applicant can respond by narrowing the invention or arguing that the PTO is wrong.  In addition, the applicant can submit evidence of certain factors that the courts have held are relevant, objective indicia of nonobviousness.  These factors are called “secondary considerations.”  They include evidence of: unexpected results, commercial success, long-felt but unsolved needs, failure of others, skepticism of experts, and copying by competitors.Continue Reading Copying by Competitors is Evidence of Nonobviousness of an Invention

To use a textbook or other reference to challenge the validity of a patent in a petition for inter partes review (“IPR”), the textbook must have been “publicly accessible” prior to the date of the challenged patent to qualify as a printed publication. Is a copyright notice sufficient evidence that a textbook was publicly accessible? The short answer is no in most, if not all, cases.  In Hulu, LLC v. Sound View Innovations, LLC, the PTAB denied Hulu’s IPR petition on the ground that Hulu had not provided sufficient evidence to show that a prior art textbook with copyright and ISBN dates was publicly available as of those dates.  As a result, Hulu requested rehearing of the PTAB decision denying institution of inter partes review of the validity of Sound View’s patent, U.S. Patent No. 5,806,062.  Hulu argued the decision was in conflict with other PTAB decisions “involving the public availability of an asserted ‘printed publication.’”

The priority date of a patent is an important aspect in protecting intellectual property. The priority date is the earliest possible filing date that a patent application is entitled to rely on; it is based on the filing dates of any related patent applications that were filed before the application (the priority chain).  This date determines which prior art can be used by the Patent and Trademark Office to determine patentability of the invention and which prior art can be used by competitors to challenge the patent’s validity.

When sued for patent infringement, a defendant can still petition for inter partes review (“IPR”) of the asserted patent at the United States Patent and Trademark Office (“USPTO”) if the petition is filed within one year of service of the complaint.  But, as Game & Technology Co. v. Wargaming (Fed. Cir. 2019) reminds us, a plaintiff must properly serve the complaint to trigger the one-year deadline.  Specifically, “[s[ection 315(b) states that ‘[a]n inter partes review may not be instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner … is served with a complaint alleging infringement of the patent.’”  35 U.S.C. § 315(b).

Many resources are being devoted to preventing data breaches and protecting privacy.  In fact, patents have issued on various approaches.  But are those approaches really patentable?   In a recent challenge to OneTrust’s patent, which is related to data privacy risk, the Patent Trial and Appeal Board (“PTAB”) found the subject matter patent ineligible.

OneTrust’s patent, U.S. Patent No. 9,691,090 (“’090 Patent”), relates to privacy management software that calculates the risk to personal data that has been collected and is being used, for example, by a business.  OneTrust explained its software platform is used by companies to comply with data privacy regulations.
