Connectics Corp. v. Pentech Pharmaceuticals

May 8, 2009


The opinion of the court was delivered by: Hon. Harry D. Leinenweber


This suit began on April 18, 2008, when Plaintiffs Connetics Corporation and Stiefel Research Australia Pty. Ltd. (collectively, the "Plaintiffs") alleged that Defendants Pentech Pharmaceuticals, Inc., Cobrek Pharmaceuticals, Inc., and Cipla, Ltd. (collectively, the "Defendants") had infringed a patent they own. Now before the Court is Defendants' Motion for Leave to File an Amended Answer, Affirmative Defenses, and Counterclaims (Docket No. 56, which corrects the main document in Docket No. 53). For the following reasons, the motion is granted.


In October 2000, Plaintiffs' predecessors received Patent No. 6,126,920 ("the '920 patent") on the drug OLUX®, which is used for the treatment of scalp dematoses and non-scalp psoriasis. See Am. Compl. ¶¶ 13-16. Defendant Pentech filed an Abbreviated New Drug Application (the "ANDA") with the Food and Drug Administration under 21 U.S.C. § 355(j) seeking approval to market a generic version of OLUX® before the expiration of the '920 patent. Id. at ¶ 17. In April 2008, after learning of the ANDA application, Plaintiffs brought this suit against Defendants for infringing the '920 patent. Plaintiffs filed an amended complaint on September 23, 2008, and Defendants filed an amended answer containing affirmative defenses and counterclaims on October 24, 2008.

On February 11, 2009, Defendants filed a motion to amend the answer to add two new defenses and counterclaims: (1) invalidity pursuant to 35 U.S.C. § 112 ¶ 1 (35 U.S.C. § 112 ¶ 1 states "The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention."); and (2) unenforceability due to inequitable conduct before the United States Patent and Trademark Office (the "USPTO"). These amendments are based on information that Defendants obtained in depositions of two of Plaintiffs' witnesses, Albert Abram, a scientist involved in the development of the patented formulation, and Julie Jones, an inventor, which took place on December 4 and 9, 2008. In those depositions, Defendants learned that Abram and Jones were aware of a 1981 article in the International Journal of Pharmaceutics by Hans Bundgaard and Jens Hansen entitled Studies on the Stability of Corticosteroids VI. Kinetics of the Rearrangement of Betamethasone-17-Valerate to the 21-Valerate Ester in Aqueous Solution, 7(3) Int'l J. of Pharmaceutics 197-203 (1981) ("the Bundgaard Article") that was not disclosed to the USPTO during the application process for the '920 patent. Based on this revelation, Defendants claim that Plaintiffs' attorneys or agents made material misrepresentations, submitted false information to the USPTO, and/or failed to disclose material information to the USPTO, including material prior art in the form of Bundgaard Article. See Defs.' Mem. in Support of their Mot. for Leave to File their Am. Answer, Aff. Defenses and Counterclaims ("Defs.' Mem.") at 6. Defendants state that they also learned in these depositions that the patent failed to meet the requirements of 35 U.S.C. § 112 ¶ 1, and is therefore invalid.

On July 22, 2008, Judge James Moran issued a discovery schedule setting deadlines of February 7, 2009 to amend the pleadings and June 12, 2009 for the close of fact discovery. See Docket No. 31. On July 29, 2008, Docket No. 31 was corrected, moving back the deadline to amend the pleadings to February 27, 2009. See Docket No. 33. On April 21, 2009, the parties' joint motion to extend fact discovery until August 14, 2009 was granted.

See Docket No. 63. On April 24, 2009, the case was reassigned to this Court for all further proceedings. See Docket No. 68.

Defendants filed the instant motion on February 11, 2009, in advance of the deadline to amend the pleadings pursuant to Judge Moran's corrected order. Evidently neither party noticed the correction to the docket, and their briefs assume that the motion was filed after the applicable deadline. Because the appropriate standard is less stringent than that discussed in the briefs, this Court will decide the motion based on the existing briefs.


Federal Rule of Civil Procedure 15 provides that a party may amend its pleading after a responsive pleading has been served with the opposing party's written consent or the court's leave. FED. R. CIV. P. 15(a). "The court should freely give leave when justice so requires." Id. Although the rule reflects a liberal attitude toward the amendment of pleadings, courts have the discretion to deny a proposed amendment if the moving party has unduly delayed in filing the motion, if the opposing party would suffer undue prejudice, or if the pleading is futile. Campania Management Co., Inc. v. Rooks, Pitts & Poust, 290 F.3d 843, 849-50 (7th Cir., 2002) (citing Foman v. Davis, 371 U.S. 178, 181-82 (1962)). Here, Defendants contend that they should be permitted to amend their answer because of the information they learned in the two depositions taken in December 2008. Plaintiffs oppose the motion on the grounds of undue delay, prejudice, and futility.

A. Delay

Delay alone is typically not a sufficient reason to deny a motion to amend. Dubicz v. Commonwealth Edison Co., 377 F.3d 787, 792 (7th Cir., 2004). However, delay may suffice if the effect of granting the motion would be to prejudice other party. See 6 CHARLES ALAN WRIGHT, ARTHUR R. MILLER & MARY KAY KANE, FEDERAL PRACTICE AND PROCEDURE § 1488, at 661-62 (2d Ed. 1990) ("FEDERAL PRACTICE AND PROCEDURE"); Park v. City of Chicago, 297 F.3d 606, 613 (7th Cir., 2002).

Plaintiffs claim that the depositions revealed no new information because neither Abram nor Jones could recall specific facts about how they used the Bundgaard Article before the patent application was filed. Pls.' Resp. in Opp'n at 6. Plaintiffs further argue that they produced the Bundgaard Article and documents relating to the container for the patented formulation (which relate to Defendants' added claims of invalidity) on May 12, 2008 as part of discovery in a related case in this judicial district involving the same patent and parties, but a different generic drug. See Connetics Corp., et al. v. Pentech Pharms., Inc. et al., Case No. 07-CV-6297 (Gottschall, J.). The parties have agreed that discovery from the case before Judge Gottschall may be used in this case. Defendants have therefore been on notice for seven months of the material underlying the amendments they now seek.

Defendants admit that Plaintiffs produced the relevant documents before the depositions, but contend that only after they took the two depositions did the new defenses and counterclaims "crystallize." Defs.' Reply at 4-7. Defendants point to portions of the testimony in which the deponents acknowledged discussing and/or using information from the Bundgaard Article prior to the filing of the patent application. Id. at 5-6. The depositions assured them of the evidentiary support they needed to include these new counts, particularly in light of the requirement that the elements of inequitable conduct must be ...
