Written Description Requirement: Ariad v. Eli Lilly

I recently had the opportunity to listen in on PLI’s one hour briefing titled Ariad v. Eli Lilly and the Separate Written Description Requirement. This briefing was conducted by Vera M. Elson, a partner in the international law firm McDermott Will & Emery and Burt Magen, a partner in the law firm Vierra Magen Marcus & DeNiro LLP.  Ms. Elson focuses her practice on intellectual property trial and counseling for her firm’s technology clients.  Mr. Magen focuses his practice on intellectual property counseling and patent prosecution for his firm’s technology clients.

Elson began by explaining that pre-Ariad § 112, ¶1 focused on two underlying purposes behind a separate written description.  The first was Possession:  “The purpose of the written description requirement is broader than to merely explain how to make and use; the applicant must also convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention.” Vas-Cath, Inc. v. Mahurkar, 935 F. 2d 1555 (Fed. Cir. 1991).  In other words, what you claimed you actually invented.  The second was Meaningful Disclosure: “A patent specification must convey the detailed identity of an invention, thereby serving a teaching function as a quid pro quo in which the public is given meaningful disclosure in exchange for being excluded from practicing the invention for a limited period of time. Univ. of Rochester v. G.D. Searle & Co., Inc. 358 F. 3d 916, 921 (Fed. Cir. 2004).  That is to say, you actually invented what you say you invented and you taught it to us.  But, everything came to a head with the Ariad case. (more…)

Top 10 Patent Issues for Patent Practioners

I recently asked Thomas Creel, of Thomas L. Creel P.C., former patent law professor for 20 years at Columbia University Law School, that with all the latest developments in the patent community including the rebirth of patent reform, the recent court cases regarding what is patentable subject matter and the proposed changes in PTO procedures, what are the top 10 areas of interest for Patent  Practioners right now?  Here is what he had to say….

1.  Economy – There’s been a lot of talk about how the economy has and is changing the practice of law, particularly in private practice. For example, new billings methods have been proposed to replace the hourly billing traditional system. Have there been discernable economic and structural changes which have affected the patent practitioner, and how are they likely in the future to affect him or her?  For example, what is the future of the big boutique law firms (such as Finnegan, Henderson; Kenyon & Kenyon; Fitzpatrick, Cella, etc.) vs. the IP sections of large general firms?  How about large corporations- has the economy affected the filing of patent applications or the handling of litigation?  Another aspect of this might be what the average charge is for prosecution, litigation, licensing, etc. (more…)
