MEMORANDUM AND ORDER
Plaintiff Sprint has filed suit against defendants Theglobe.com, Inc. and Voiceglo Holdings, Inc. (collectively, “TGCI”), as well as Vonage Holdings, Corp. and Vonage America, Inc. (collectively, “Vonage”). Sprint alleges that each of the defendants has infringed seven of its telecommunications patents. This matter comes before the court on three pretrial motions (documents 24, 26, and 32). TGCI requests that the court sever the case into separate proceedings because TGCI has been improperly joined with Vonage. Additionally, Sprint contends that the court should strike Vonage’s first affirmative defense and third declaratory counterclaim for failure to provide sufficient detail.
ANALYSIS
1. Motion to Sever the Parties Based on Improper Joinder
TGCI argues that its joinder in Sprint’s suit against the two Vonage defendants violates the permissive joinder requirements of Fed.R.Civ.P. 20. Rule 20 provides in part:
All persons ... may be joined in one action as defendants if there is asserted against them jointly, severally, or in the alternative, any right to relief in respect of or arising out of the same transaction, occurrence, or series of transactions or occurrences and if any question of law or fact common to all defendants will arise in the action.
The drafters devised Rule 20(a) “to promote trial convenience and expedite the final determination of disputes, thereby preventing multiple lawsuits.” 7 Charles Alan Wright, Arthur R. Miller & Mary Kay Kane, Federal Practice and Procedure § 1652 (3d ed.2001). The court construes Rule 20(a) broadly because “joinder of claims, parties, and remedies is strongly encouraged.” Biglow v. Boeing Co.,
Applying the facts of this ease to Rule 20’s two-part standard, at least at this pretrial juncture, the court finds that it is proper to join Sprint’s claims against the Vonage defendants with its claims against TGCI. The first requirement is met because Sprint’s claims against all the defendants arise out of the same transaction or occurrence. Most notably, Sprint alleges that each of the defendants has infringed the same seven patents. Further, the defendants have raised several identical affirmative defenses. As a result, it is undeniable that the court will inevitably be faced with duplicative arguments and overlapping evidence. As to the second requirement, there are numerous common issues of law and fact, both in addressing Sprint’s proof of infringement as well as the defendants’ affirmative defenses. Many of the issues in dispute are purely issues of law, and obviously the court will apply the same ruling to each defendant.
TGCI argues that it is inherently unfair to join separate defendants in the same proceeding when they are competitors. If the court were to accept this unsupported assertion, however, the court would nullify the primary purpose behind Rule 20, which is to join separate defendants if the joined suits have overlapping issues. That Vonage and TGCI are competitors who allegedly have infringed the same patents enhances, rather than undermines, the rationale for permissive joinder in this matter.
In a recent patent case, the court in MyMail, Ltd. v. America Online, Inc.,
This court finds the above analysis particularly persuasive to the undeveloped record in this matter. As Sprint contends, TGCI cannot support any of its assertions why pretrial proceedings should not be joined. TGCI alleges that it will improperly burdened by having to attend depositions relating to Vonage, but its attendance is not mandatory. Joinder permits but does not require participation.
Beyond judicial economy, TGCI also ignores the likelihood that severing the claims before trial would produce inconsistent pretrial rulings, particularly in construing the patents pursuant to Markman v. Westview Instruments, Inc.,
The court will revisit the choice of severing the proceedings in connection with the final pretrial conference if requested, but denying the motion to sever until the parties have completed discovery is appropriate. At this point, TGCI’s motion is premature.
2. Motion to Strike
In addition to defending the motion to sever, Sprint also has moved to strike Vonage’s first affirmative defense and third declaratory counterclaim. Vonage’s first affirmative defense states: ‘Vonage is informed and believes that [Sprint’s seven patents], and each of the seven claims thereof, are invalid, void and/or unenforceable under one or more of the sections of Title 35 of the United States Code.” Its third declaratory counterclaim alleges that the patents are unenforceable and incorporates, by reference, its affirmative defenses.
In analyzing Sprint’s motion to strike, Fed. R. Civ. Pro. 8 governs the court’s analysis. See Mayle v. Felix, — U.S.-,-,
Simply examining the first affirmative defense on its face, it is immediately apparent that Vonage has not met the minimal pleading requirements of Rule 8. As Sprint explains, Title 35 of the United States code includes 112 discrete sections. It is unreasonable to make Sprint guess which of these sections Vonage is relying upon to contend that Sprint’s patent claims are unenforceable.
[T]he court agrees that such general, conclusory allegations are insufficient because they do not provide fair notice of plaintiffs claims. In Qarbon.com Incorporated, v. eHelp Corporation,315 F.Supp.2d 1046 (N.D.Cal.2004), a defendant filed a counterclaim alleging that “the ’441 patent is invalid and void under the provisions of Title 35, United States Code §§ 100 et seq., and specifically §§ 101, 102, 103 and/or 111____” The court held that simply pleading the statute to allege patent invalidity was “radically insufficient” because it did not provide the other party with a basis for assessing the claim. “Effective notice pleading should provide the defendant with a basis for assessing the initial strength of the plaintiffs claim, for preserving relevant evidence, for identifying any related counter-or cross-claims, and for preparing an appropriate answer.” Similarly, in Advanced Cardiovascular Systems, Inc. v. Medtronic Inc.,41 U.S.P.Q.2d 1770 ,1996 WL 467273 (N.D.Cal.1996), the court struck an affirmative defense alleging patent invalidity “for failure to satisfy the requirements of patentability contained in Title 35, United States Code, including but not limited to, section 101, 102, 103 and/or 112,” because these sections provide numerous grounds for invalidating a patent, and thus the plaintiff was not provided fair notice of the basis for this defense.
Id. at *3.
Because the challenge is exactly the same in this case, the court is persuaded to follow the cogent analysis of the above line of cases. Moreover, Sprint correctly distinguished the cases cited by Vonage and demonstrated as a matter of law that the first affirmative defense and third declaratory counterclaim are fatally vague. Cf. Resolution Trust Corp. v. Thomas,
The court also readily concludes that Vonage should be granted leave to amend. The Tenth Circuit has advised that leave to amend should be denied “only on ‘a showing of undue delay, undue prejudice to the opposing party, bad faith or dilatory motive, failure to cure deficiencies by amendments previously allowed, or futility of amendment.’ ” Duncan v. Manager, Dept. of Safety, City and County of Denver,
Conclusion
For the reasons set forth above, the court denies the motion to sever based on improper joinder of parties because TGCI’s motion is premature at this pretrial stage of the proceedings. Further, the court grants Sprint’s motion to strike both Vonage defendants’ first affirmative defense and third declaratory counterclaim because they fail to afford Sprint enough detail to draft an answer, but with leave to amend as set forth below.
IT IS THEREFORE ORDERED BY THE COURT that the motion to sever based on improper joinder (doc. 32) is denied, and the motions to strike the first affirmative defense and third declaratory counterclaim (doc. 24 and doc. 26) are granted, with leave to file an amended answer and counterclaims no later than February 26, 2006.
Notes
. Sprint actually filed separate motions to strike against Vonage America and Vonage Holdings. Because the arguments advanced by the parties are identical in each motion, however, the court will address them collectively and refer to both Vonage defendant entities as "Vonage."
. TGCI's general allusion to pretrial proceedings, which could include motion practice or court appearances, as a potential burden virtually does not merit discussion. Plaintiff’s motions directed at Vonage here impose a de minimis expense on TGCI and court proceedings short of trial would not be lengthened significantly.
