Having fully considered the parties’ arguments and for the reasons set forth herein, the Court hereby GRANTS IN-PART and DENIES-IN-PART Defendants’ motion.

BACKGROUND

On June 1, 2007, Plaintiff filed the instant suit against Defendants alleging infringement of U.S. Patent No. 6,757,322 (“the '322 patent”). The '322 patent teaches a system and method for transmitting a plurality of spread-spectrum signals, radiated by a plurality of antennas, over a communications channel having fading. The asserted claims of the '322 patent teach wireless communications systems and methods using multiple transmission and reception antennas in order to overcome fading and shadowing effects found in a multipath environment.

*706 Plaintiff asserts four claims of the '322 patent: claims 1, 9, 25, and 33. On March 13, 2008, Plaintiff served its “Disclosure of Asserted Claims and Infringement Contentions” pursuant to Patent Rule 3-1. Motion, Exh. B-K. Plaintiffs Infringement Contentions list a significant number of Accused Products including, among others, wireless routers, wireless networking cards, and laptop computers that comply with the IEEE 802.11n wireless networking draft standard. 2

On July 11, 2008, Defendants filed the instant motion to strike Plaintiffs Infringement Contentions, or in the alternative requesting an order to compel Plaintiff to provide Infringement Contentions that comply with Patent Rule 3-1. Defendants assert that Plaintiffs Infringement Contentions fail to satisfy Patent Rule 3-1.

LEGAL STANDARD

Pursuant to Rule 83 of the Federal Rules of Civil Procedure, this Court has adopted Local Patent Rules to assist with case management in patent cases. Fed. R.Civ.P. 83; Computer Acceleration Corp. v. Microsoft Corp., 503 F.Supp.2d 819, 821 (E.D.Tex.2007) (Clark, J.) (recognizing adoption of Local Patent Rules as valid exercise of a court’s authority). The Local Patent Rules “exist to further the goal of full, timely discovery and provide all parties with adequate notice and information with which to litigate their cases.” Computer Acceleration, 503 F.Supp.2d. at 821 (citations omitted).

Patent Rule 3-1 provides that any party “claiming patent infringement must serve on all parties a ‘Disclosure of Asserted Claims and Infringement Contentions.’ ” Patent Rule 3-1. Additionally, Patent Rule 3-1 delineates all of the information that such Infringement Contentions must contain, including a list of each claim of each patent asserted to be infringed; each accused product; and each element of each asserted claim and the corresponding structure or step within the accused product. Patent Rule 3-l(a)-(c). Patent Rule 3-1 goes on to provide, “[separately for each opposing party, the [Infringement Contentions] shall contain ... [a] chart identifying specifically where each element of each asserted claim is found within each Accused Instrumentality.” Patent Rule 3-1 (b).

The Patent Rules require plaintiffs to “set forth specific theories of infringement at the outset of the case” utilizing all publicly available information. Orion IP, LLC v. Staples, Inc., 407 F.Supp.2d 815, 817 (E.D.Tex.2006) (Davis, J.) (citing Am. Video Graphics, L.P. v. Elec. Arts, Inc., 359 F.Supp.2d 558, 560 (E.D.Tex.2005) (Davis, J.)). Enough specificity is required to give an alleged infringer notice of the patentee’s claims. Computer Acceleration, 503 F.Supp.2d at 823; see also Orion, 407 F.Supp.2d. at 817 (citing Connectel, LLC v. Cisco Systems, Inc., 391 F.Supp.2d 526, 527-28 (E.D.Tex.2005) (Davis, J.)).

DISCUSSION

Defendants make a number of arguments in support of the motion. First, Defendants argue that Plaintiffs use of the 802.1In standard as a basis for its Infringement Contentions is inadequate under the Patent Rules. Second, Defendants argue that Plaintiffs Infringement Contentions consist of one generic claim chart for each Defendant, failing to take into account the differences that exist among each Accused Product. Finally, Defendants’ remaining arguments are directed *707 to specific claim limitations. Each argument mil be addressed in turn.

I. Infringement Contentions Based on the 802.11n Draft Standard

The Accused Products include not only-products compliant with the 802.11n draft standard, but also products which are compliant with other 802.11 standards, specifically b and g. 3 The following section, 1(A), infra, discusses the 802.1ln-compliant Accused Products, while all other Accused Products are discussed in section 1(B), infra.

A. 802.11n-Compliant Accused Products

Defendants first argue that the overarching problem with Plaintiffs Infringement Contentions is the use of the 802.11n standard as a baseline for its Infringement Contentions. Motion at 7. Defendants assert that Plaintiffs Infringement Contentions are vague and conclusory, and even if the use of the 802.11n standard was sufficient, Plaintiff has failed to specifically identify where each claim limitation corresponds to a particular specification in the 802.11n draft standard. Id. at 8.
