There are a number of requirements that must be met for an invention to be patentable. The invention must be novel (unique) and nonobvious (i.e., a person skilled in the field of the invention would not have found the invention obvious based on the existing knowledge in the field). In addition, the patent application must meet other requirements, including written description (the application must contain a detailed, clear, and definite written description of the invention) and enablement (the application must describe how to make and use the invention). If the patent application satisfies all of the requirements, a patent is issued.

A third party can challenge an issued patent on several different grounds, either in litigation or in the Patent and Trademark Office’s Patent Trial and Appeal Board (PTAB). If the challenge is successful, some or all of the patent’s claims will be invalidated. If only some of the claims are invalidated, those claims will be canceled from the patent and the remaining claims will be enforceable.

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 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.
