Winter 2018 (snippets)
This article focuses on different standards for infringement of software patents based on whether the patent has method, system, or CRM claims, and explains the practical implications of these differences.
Winter 2017 (snippets)
Although the PTAB has instituted CBM trials for patents that do not facially qualify as business method patents, recent Federal Circuit decisions have required a more strict reading of the AIA statute in instituting CBM trials.
Spring 2016 (snippets)
The “on-sale” bar to patentability refers to a sale or offer for sale of an invention that can invalidate the patent for that invention. The America-Invents-Act (AIA), which altered the language in the statutes that apply to the on-sale bar, has made it difficult to determine what actions might constitute a “sale” or an “offer for sale” under current law. Nevertheless, a clear understanding of the on-sale bar is necessary to enable entities of all sizes—from single inventors to large corporations—to effectively monitor activities surrounding their inventions, and to enable attorneys to provide such entities with accurate and useful advice.
Spring 2015 (snippets)
The recent interpretation of patent eligible subject matter under 35 U.S.C. § 101 by the Supreme Court in Alice v. CLS Bank in June 2014 has caused confusion in the patent world regarding the validity and practicality of software and business method patents. In Alice, the Supreme Court held that claims directed towards a computer-implemented means of mitigating settlement risk by using a third-party intermediary did not qualify as eligible subject matter.
November 17, 2014

Prior to filing a patent application at the United States Patent and Trademark Office (“USPTO”), an applicant seeking patent protection for an invention should consider conducting a prior art search. Also known as a patentability search, a prior art search involves discovering and examining art, such as issued patents, published patent applications, and other published documents, that can affect the potential to obtain a patent on the invention. More exhaustive prior art searches may also include discovering and examining any prior uses or prior sales of technology related to the invention.

Spring 2014 (snippets)
Patent claim drafting is a challenging exercise that requires balancing potential infringement of the claim against the prior art. A patent practitioner may easily draft a claim of very narrow scope, but if such claim has a low likelihood of being infringed, the value of the claim is extremely diminished.
