Before 1995, the term of a U.S. utility patent was 17 years from the day the patent issued.  In 1994, the federal statutes were changed to make the patent term 20 years from the effective filing date of the patent application.  This change was part of the Uruguay Round Agreements Act and was intended to make U.S. patents comparable to foreign patents, which, in most countries, expire 20 years from their filing dates.

However, in order to address the problem of delays caused by the Patent and Trademark Office during the prosecution of a patent, Congress enacted statutes providing for the addition of specific numbers of days to a patent’s term.  See 35 U.S.C. section 154(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.

In Curver Luxembourg SARL v. Home Expressions Inc., case number 18-2214, the U.S. Court of Appeals for the Federal Circuit recently held that the claim language of a design patent can limit its scope where the claim language supplies the only instance of an article of manufacture that appears nowhere in the figures.

Plaintiff Curver had asserted U.S. Design Patent No. D677,946 (’946 patent), entitled “Pattern for a Chair” and claiming an “ornamental design for a pattern for a chair.” Curver sued defendant Home Expressions alleging that Home Expressions made and sold baskets that incorporated Curver’s claimed
design pattern and thus infringed the ’946 patent. The design patent’s figures, however, merely illustrate the design pattern disembodied from any article of manufacture.

Have you ever driven away from your home and then had that irritating doubt in your mind as to whether you remembered to close your garage door? I know I have. No matter how hard I try to search my brain’s archives, I really don’t remember whether I closed the garage door even though I close it 99.9% of the time! In that moment, you wish there was a way to check that doesn’t require turning around and going back home to see if you really left the house wide open for anyone to walk in.

Well The Chamberlain Group, Inc. (“Chamberlain”) thought it had patented an invention that could help with this type of problem—a garage door opener that wirelessly transmits information such as whether the door is open or closed. See U.S. Patent No. 7,224,275 (the “’275 Patent”). Specifically, the patent “relates to an apparatus and method for communicating information about the status of a movable barrier, for example, a garage door.”

In CELGENE CORPORATION v. PETER, the Federal Circuit recently affirmed the PTAB’s decisions finding appealed claims obvious. However, more importantly, the Federal Circuit also held that the retroactive application of IPR proceedings to pre-AIA patents is not an unconstitutional taking under the Fifth Amendment.

Regarding the constitutional issue of whether the retroactive application of IPRs to pre-AIA patents is an unconstitutional taking, the Federal Circuit noted that The Supreme Court left open this challenge with
the following passage near the end of its decision in Oil States Energy Servs., LLC v. Greene’s Energy Grp., LLC, 138 S. Ct. 1365, 1379 (2018) as follows:
