USPTO Releases New Business Method Guidelines: Requires “physical transformation” or “concrete and tangible result”

Patent, Patent Prosecution, , ,

In the wake of the Lundgren case, the USPTO has released a set of interim examination guidelines for determining subject matter eligibility of patent applications. (Link).  The guidelines will be used by examiners “in determining, on a case-by-case basis, whether a claimed invention falls within a judicial exception to statutory subject matter (i.e., is nothing more than an abstract idea, law of nature, or natural phenomenon), or whether it is a practical application of a judicial exception to statutory subject matter.”

The crux of the new guidelines is that an invention falls within the scope of 35 U.S.C. 101 “if the claimed invention physically transforms an article or physical object to a different state or thing, or if the claimed invention otherwise produces a useful, concrete, and tangible result.”  The application itself should enable one of ordinary skill in the art to understand the utility of the invention.

PTO Board: Disclosure of Sequence Enables at least 5% of Natural Variance.

Patent, Patent Cases 2005, ,

Blast_equationEx parte Bandman, No. 2004-2319, (BPAI 2005)

By Donald Zuhn

In an appeal from a final rejection, the PTO Board reversed rejections based on both the written description and enablement requirements of 35 U.S.C. § 112, first paragraph, and entered a new ground of rejection under 35 U.S.C. § 112, second paragraph one of the claims. (U.S. Application No. 09/915,694). 

Pointedly, the Board found that claims directed to a naturally occurring amino acid (or polynucleotide) sequence at least 95% identical to the disclosed amino acid (or polynucleotide) sequence were enabled and met the written description requirement.

March 2005 Report on New Academic Research

Patent, , , ,

PatentlyOImage004

Each month I post a note discussing new research from the academic side of patent law.  This March edition includes three great articles that relate to either legislative changes (prior use statute, post grant opposition) or upcoming court decisions (Phillips claim construction case).  Feel free to e-mail suggestions for April’s edition.

  1. Tom Fairhall and Paul Churilla, Prior Use of Trade Secrets and the Intersection with Patent Law, 14 Fed. Cir. Bar J. 455.  Fairhall and Churilla present a timely article on prior use rights that notes how the current prior use statute (35 USC 273) does not provide the scope necessary to truly protect a prior user’s expectations or investments.  The article is quite timely because FTC proposals to expand the statutory prior use rights is gaining some teeth in the patent community and on the Hill.
  2. Mark Lemley, The Changing Meaning of Patent Claim Terms, available at SSRN.  Professor Lemley’s article is also timely — he discusses at what particular point in time should the meaning of claim terms be fixed.  This is important because the ordinary meaning of terms in the English language change over time.  The major temporal candidates are (i) at the time of the invention (currently used for novelty and nonobviousness); (ii) at the time the application was filed (currently used for enablement or written description); (iii) a the time the patent issues (currently used for means-plus-function claim construction); and (iv) at the time of the infringement (at least some times used to determine infringement).  Lemley agrees that each candidate has a sound legal foundation.  However, he argues that the best approach moving forward is to fix the meaning at the time the patent application is first filed.
  3. Jay Kesan and Andres Gallo, Why ‘Bad’ Patents Survive in the Market, available at SSRN. The professors provide a game theory model to show how would-be invalid patents can survive and be valuable in the marketplace.  Essentially, the transaction costs make it difficult to mount an effective challenge to improperly granted patents.  Their work will serve as the theoretical basis any proposed post-grant opposition procedures.  Specifically, the authors “conclude that a low-cost, post-grant opposition process based primarily on written submissions within a limited estoppel effect . . . will serve as an effective instrument for improving the quality of patents that are issued and enforced.”

Eight is Enough: Eight important patent cases for Spring 2005

Patent, Patent Cases 2005, , , , , , , , ,

There are lots of great cases on the Federal Circuit's spring calendar.  Several cases pending at either the Federal Circuit or Supreme Court that are 'worth a special look,' according to Hal Wegner.  Here are some highlights of Mr. Wegner's list, with my own comments.

  • Merck v. Integra, Supreme Court decision by June 27, 2005.
  • LabCorp v. Metabolite, petition for cert submitted, Supreme Court has requested Solicitor General's Opinion on Cert.  The case involves a patentability question -- whether Metabolite's patented method of detecting vitamin B deficiency should be invalid as "because one cannot patent laws of nature, natural phenomena, and abstract ideas." 
  • Purdue Pharma v. Endo, CAFC heard oral arguments in early November on the question of whether patentee's conduct was 'inequitable' for failing to disclose that results used to establish patentability were prophetic rather than experimental. A decision is expected soon.
  • SmithKline Beecham v. Apotex, awaiting decision on petition for rehearing.  This case now revolves around the question of whether use of an invention to confirm utility for FDA approval is an 'experimental use' that saves a patent from anticipation under 102(b).
  • Phillips v. AWH, awaiting en banc decision on claim construction methodology.
  • Eolas Technologies v. Microsoft, Federal Circuit decision awaited, hopefully discussing the scope of 271(f). The upcoming appeal of AT&T v. Microsoft presents the same 'golden master disk' scenario as Eolas, and will become important if Eolas is decided on other grounds.
  • Independent Ink v. Illinois Tool Works, In January, the CAFC determined that, in an antitrust tying case, a patent presumptively defines the relevant market as the nationwide market for the patented product itself.  There is some potential for cert in this case.
  • NTP, Inc. v. Research in Motion, Ltd., there is a good chance for a rehearing in this case involving RIM's BlackBerry product.  This case will be important in defining extraterritorial application of U.S. patent laws in the modern era of networked computing systems.
  • In re Fisher is not yet on the CAFC calendar.  In this case, the BPAI affirmed a rejection for lack of utility and enablement (101 and 112 p1) because the specification lacked a specific teaching of a substantial utility.  According to the decision, without a specific teaching of substantial utility, then virtually all chemicals would meet the requirements of section 101 as at least "useful in research."

Although not patent litigation, Sarah Stirland (one of the few reporters focusing on intellectual property) at the National Journal has written a nice article regarding the potential for legislation in the 109th Congress.
