Written Description: Whats Up With That? Patent Law Sept. 9, 2004 Prof Merges

The Written Description Requirement Scope of enablement vs. scope of that which you have described Gentry Gallery, Inc. v. Berkline Corp., 134 F.3d 1473 (Fed. Cir. 1998). Gentry was granted a patent for a sectional sofa comprised of a pair of reclining seats that faced the same direction. Claim 1, the broadest claim, identifies a fixed console between the pair of seats. Claims 9, 10, 12-15, and are directed to a sectional sofa in which the control means are specifically located on the console. The term console does not cover a sofa section having a seat back that folds down to serve as a table top. (This was to distinguish Gentrys sofa from prior art.) The Federal Circuit limits the scope of the claim to cover sofas in which the recliner control is located on the console and invalidates 12 claims in the patent under § 112. The court affirmed that Berkline had not infringed on Gentrys patent by constructing reclining chairs separated by a center seat whose back cushion pivoted to form a table.

In re Curtis, 69 USPQ2d 1274 (CA FC 2004) 69 USPQ2D 1274 In re Curtis U.S. Court of Appeals Federal Circuit No Decided January 6, 2004

In re Curtis, contd The Board determined that Curtis could not traverse the examiners rejections by claiming the benefit of an earlier patent application because the disclosure therein failed to adequately describe the subject matter encompassed by the rejected claims under 35 U.S.C. §112, ¶ 1. Because the Boards decision is supported by substantial evidence and otherwise is in accordance with law, we affirm.

Univ of Rochester v. Searle Univ. of Rochester v. GD Searle & Co., 358 F.3d 916 (Fed. Cir. 2004) – business as usual in the application of the written description Requirement

Patent for a method of treating inflammation using inhibitors of prostaglandin H synthase-2 (PGHS-2) enzyme activity, also known as COX-2

Claimed method of using a compound acting upon a polypeptide did not comply with the written description requirement where such a compound was not disclosed. Spec. did not disclose which, if any, compounds selectively inhibit PGHS-2

Undercutting Enzo Biochem, Inc. v. Gen- Probe Inc., 296 F.3d 1316 (Fed. Cir. 2002) (Enzo II) –Deposited sequences meet written description requirement –Subsequences, mixtures, and mutations that hybridize to deposited sequences may meet WD requirement Swing back to Enzo I – very aggressive WD Requirement?

Rochester v Searle, contd Right result, wrong rationale?

Signs of Resistance I Rader, J., in Moba v. Diamond Automation, 325 F.3d 1306, 1322 (Fed. Cir. 2003): –By making written description a free-standing disclosure doctrine, this court produces numerous unintended and deleterious consequences.

Follows a similar criticism in Enzo Biochem, Inc. v. Gen-Probe, Inc., 323 F.3d 956, 976 (Fed. Cir. 2002) (Rader, J., dissenting from denial of rehearing en banc) Signs of Resistance II

Signs of Resistance III University of Rochester v. G.D. Searle & Co., Inc., 375 F.3d 1303, 71 U.S.P.Q.2d 1545 (Fed.Cir.(N.Y.) Jul 02, 2004

Rader, Gajarsa & Linn, dissenting Indeed a brief survey of the literature on this topic, an astounding amount in a few short years, shows 31 articles criticizing the Eli Lilly doctrine, 7 articles defending the doctrine, and 16 neutrally commenting on the state of this evolving case law.5 In its brief requesting en banc reconsideration in Enzo Biochem, the United States issued a call for clarity, which this court has yet to address...

Although this Court has addressed the written description requirement of section 112 on a number of occasions, its decisions have not taken a clear and uniform position regarding the purpose and meaning of the requirement.... A review of the plain text of section 112, and the case law of this Court, reveals at least three different possible tests for an adequate written description.... En banc consideration of the written description provision is appropriate so that the court can provide inventors, the public, and the USPTO with an authoritative interpretation of the provision.

Who is Judge Raders Audience? The Supreme Court? Signs of re-engagement with patent law, 1995 (Markman) (Festo) But of course, only a limited patent diet –Disappointment over Madey v. Duke Univ.

A Normative Interlude Whats wrong with the Written Description requirement? –Diversion of R&D resources...

Described in specificaction Enabled: described or discoverable without undue experimentation

What is the cost of fleshing out the disclosure? What is the value of the enabled but described embodi- ments?

Shouldnt we be encouraging the inventor to invest in the next significant (nonobvious) invention? Rather than fleshing out all the obvious variants of the last invention?

Bring Back Classical Enablement! In re Fisher, 427 F.2d 833 (CCPA 1970) –specification [must be]... Commensurate with the scope of the claims National Recovery Technologies, Inc. v. Magnetic Separation Systems, Inc., 166 F.3d 1190 (Fed Cir 1999): –The scope of the claims must be less than or equal to the scope of the enablement.
