Patent Validity

Breaking the Routine: New Guidance on Patent Eligibility

I’m kind of passionate about patent eligibility. A little weird, right? I guess when a single legal doctrine has such vast implications for the value of U.S. patents, it’s not surprising that a lot of ink is spilled on its behalf. Also, it’s an ongoing battle for some of my clients.

To date, applying the patent-eligibility law has been inconsistent at best. This kind of chaos is unsettling to inventors, companies, universities, and investors. Some recent caselaw, however, has motivated me to now spill a little more ink (albeit digital ink). In particular, the Federal Circuit and the U.S. Patent and Trademark Office have provided some guidance for applying Supreme Court precedents in determining whether certain claims are patent eligible. This may be helpful to patentees and patent applicants.

You Can't Get Anything You Want at Alice's Restaurant

This blawg is called Alice's Restaurant, and it's about Alice, and CLS Bank, but Alice's Restaurant is not the name of the case, that's just the name of the blawg, and that's why I called the blawg Alice's Restaurant. Read More...

A Myriad of Questions for Biofuel Patents

So you’ve heard about or read the AMP v. Myriad Genetics case. You know that the Supreme Court was asked whether “human genes are patent eligible.” You’re wondering whether it will affect the biofuel patent estates that are near and dear to your heart (or perhaps not so dear). My answer to your question is a most definite “maybe.”

Evaluating a Company's Patent Position

In December, 2012, ExecSense, the world's largest publisher of professional webinars, eBooks & more, published my eBook, Evaluating a Company’s Patent Position. The following is the Executive Summary:

There are many reasons that patent attorneys may be asked to conduct diligence reviews of a company’s patent estate. Investors may seek to take an equity position. Banks may seek to extend loans. Other companies may seek to acquire the company, its assets, or start a joint venture. Evaluating a company’s patent position is a complex matter with many moving parts. It is much like peeling an onion where each bit of information may open up a new line of inquiry. While some parts of the process should be accomplished early, there is no strict chronological order in which the steps of the investigations unfold.

Broadly speaking, the steps in a patent diligence evaluation require multiple lines of inquiry. The attorneys investigate the company’s patent rights and the content of the underlying patent families. Also, the company’s products, services, R&D, and commercial timelines – as well as those of its competitors – must be ascertained. These should be compared with the company’s patented and pending claims. Also, the attorneys should investigate the validity and enforceability of the company’s patents and any relevant litigation. All this should be accomplished while preserving confidential information and the attorney-client privilege.

This chapter is not a do-it-yourself guide on patent diligence. There are too many complex issues and concerns about the facts, the law, confidentiality, and the attorney client privilege for anybody but a competent attorney – or team of attorneys – to tackle. Rather, I hope that the following narrative helps educate the consumers of patent diligence.

Publish And Perish: The Tension Between Publishing And Patenting

In re Droge serves as a cautionary reminder to those who manage the publication policies of inventors. In this case, one of the inventor’s own prior publications was used to find that the claimed invention was obvious. Thus, it is critical to manage inventor publication activities to minimize the risk of creating prior art against your own patents. Some guiding principles are provided for patent professionals or others that seek to manage publication policies. Read More...
