Program Materials

This CLE webinar will provide guidance to patent counsel on leveraging decisions by the Court of Customs and Patent Appeals (CCPA) and the Federal Circuit regarding application of §112 written description. The panel will examine lessons learned through CCPA and early Federal Circuit decisions and offer strategies to overcome the challenges of §112.

Description

Federal Circuit patent decisions, such as Adrian Rivera v. ITC, as well as important decisions such as Rochester and Ariad, demonstrate that §112(a) (para. 1 pre-AIA) issues remain a constant challenge for practitioners.

The CCPA developed a rich body of §112 jurisprudence, which the Federal Circuit adopted as binding precedent, providing a treasure trove of arguments for practitioners prosecuting, defending before PTAB in AIA post-grant proceedings, and litigating patents in the face of assertions of lack of written description support and lack of enablement.

Counsel can draw on CCPA cases and early Federal Circuit cases for guidance in presenting evidence and arguments of written description support and enablement.

Listen as our authoritative panel of U.S. patent attorneys examines the lessons from select CCPA and early Federal Circuit decisions (still cited in the Manual of Patent Examining Procedure, MPEP), as well as by the recent §112 Federal Circuit decisions, to avoid repeating past mistakes and to truly promote the progress of the useful arts and sciences as mandated by the Constitution.

Outline

  1. Lessons from the CCPA and early Federal Circuit decisions that reversed §112 rejections/invalidity holdings
    1. In re Schechter, 205 F.2d 185, 98 USPQ 144 (CCPA 1953) (claim rejected as improper Markush; reversed)
    2. In re Robins, 429 F.2d 452, 166 USPQ 552 (CCPA 1970) (examples not required)
    3. In re Borkowski, 422 F.2d 904, 164 USPQ 642 (CCPA 1970) (“magical relation between the number of representative examples and the breadth of the claims”)
    4. In re Brower, 433 F.2d 813, 167 USPQ 684 (CCPA 1970) (patent application found enabled for priority date benefit)
    5. In re Oda, 443 F.2d 1200, 170 USPQ 268 (CCPA 1971) (correcting obvious error not new matter)
    6. In re Marzocchi, 439 F.2d 220, 169 USPQ 367 (CCPA 1971) (“first paragraph of § 112 requires nothing more than objective enablement. How such a teaching is set forth, either by the use of illustrative examples or by broad terminology, is of no importance.”)
    7. In re Moore, 439 F.2d 1232, 169 USPQ 236 (CCPA 1971) [analyze 112(b) first (rejection at issue is one for indefiniteness)]
    8. In re Gardner, 475 F.2d 1389, 177 USPQ 396 (CCPA 1973) (meeting “how-to-use” requirement)
    9. In re Smythe, 480 F.2d 1376, 178 USPQ 279 (CCPA 1973) (liquids and gases other than air)
    10. In re Angstadt, 537 F.2d 498, 190 USPQ 214 (CCPA 1976) (not required to test every species covered by a claim)
    11. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976) (range)
    12. In re Johnson, 558 F.2d 1008, 194 USPQ 187 (CCPA 1977) (proviso)
    13. In re Hogan, 559 F.2d 595, 194 USPQ 527 (CCPA 1977) (date benefit)
    14. In re Harnisch, 631 F.2d 716, 206 USPQ 300 (CCPA 1980) (improper Markush groups)
    15. In re Breslow, 616 F.2d 516, 205 USPQ 221 (CCPA 1980) (enabled)
    16. In re Rasmussen, 650 F.2d 1212, 211 USPQ 323 (CCPA 1981) (claim may be broader than the specific embodiment disclosed in a specification)
    17. In re Bundy, 642 F.2d 430, 209 USPQ 48 (CCPA 1981) (how-to-use requirement of the first paragraph of §112 has been adequately complied with)
    18. In re Marosi, 710 F.2d 799, 218 USPQ 289 (CCPA 1983) (sufficiently enabled; “appellants’ invention does not reside in such a number”)
    19. L. Gore & Associates Inc. v. Garlock Inc., 721 F.2d 1540 (Fed. Cir 1983) (“no evidence and no finding that those skilled in the art would have found the specification non-enabling”)
    20. Atlas Powder Co. v. E.I. duPont de Nemours & Co., 750 F.2d 1569, 224 USPQ 409 (Fed. Cir. 1984) (“Even if some of the claimed combinations were inoperative, the claims are not necessarily invalid”)
    21. Cross v. Iizuka, 753 F.2d 1040 (Fed. Cir. 1985) (“how-to-use” requirement met)
    22. Spectra-Physics Inc. v. Coherent Inc., 3 USPQ2d 1737 (Fed. Cir. 1987), cert. denied, 484 U.S. 954 (1987) (enabled but failed to disclose best mode)
    23. In re Wands, 858 F.2d 731, 8 USPQ2d 1400 (Fed. Cir. 1988) (some experimentation okay)
    24. Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555, 19 USPQ2d 1111 (Fed. Cir. 1991)
    25. In re Brana, 51 F.2d 1560, 34 USPQ2d 1437 (Fed. Cir. 1995) (PTO has the initial burden of challenging a presumptively correct assertion of utility in the disclosure)
  2. Recent §112 Federal Circuit decisions
    1. Univ. of Rochester
    2. Ariad

Benefits

Our panel will review these and other important issues:

  • What lessons can patent counsel draw from CCPA decisions when making arguments of written description support and enablement?
  • What steps can counsel for patentees take to meet the written description and enablement requirements and withstand invalidity/unpatentability challenges based on written description and enablement?
  • What steps should patent counsel take going forward to avoid repeating mistakes of the past?
