SAN JOSE DIVISION

GREGORY BENDER,

Plaintiff,

LABORATORIES, INC.,

No. C09-02112 JW (HRL)

ORDER DENYING SILICON

LABORATORIES’ MOTION TO

STRIKE AND GRANTING SILICON

LABORATORIES’ MOTION TO

COMPEL

[Re: Docket No. 27]

Plaintiff Gregory Bender sues for alleged infringement of his U.S. Patent No. 5,103,188

(the “‘188 patent”), which concerns circuits for amplifying complex or high speed signals. 

Defendant Silicon Laboratories, Inc. (“Silicon Labs”) moves to strike Bender’s infringement

contentions, or alternatively, to compel amended contentions. Upon consideration of the

moving and responding papers, as well as the arguments presented at the March 16, 2010

hearing, this court denies the motion to strike and grants the motion to compel.

Patent Local Rule 3-1 requires a plaintiff in a patent infringement action to serve

infringement contentions setting forth “[e]ach claim of each patent in suit that is allegedly

infringed by each opposing party” and identifying for each asserted claim “each accused

apparatus, product, device, process, method, act, or other instrumentality (“Accused

Instrumentality”) of each opposing party of which the party is aware.” PATENT L.R. 3-1(a),

(b).1

 A plaintiff must also provide a “chart identifying specifically where each limitation of

each asserted claim is found within each Accused Instrumentality, including for each limitation

that such party contends is governed by 35 U.S.C. § 112(6), the identity of the structure(s),

act(s), or material(s) in the Accused Instrumentality that performs the claimed function.” Id. at

3-1(c).

Patent L.R. 3-1 is essentially a “discovery device” intended to streamline the discovery

process by taking the place of a series of interrogatories that defendants would likely have

propounded. Network Caching Technology LLC v. Novell, Inc., No. C01-2079VRW, 2002 WL

32126128, *3-4 (N.D. Cal., Aug. 13, 2002). As such, a plaintiff is required to include its in

infringement contentions all facts known to it, including those discovered in its Fed. R. Civ. P.

11 pre-filing investigation. Id. at *4. The Rules are designed to require parties to crystallize

their theories of the case early in the litigation and to adhere to those theories once they have

been disclosed. Alberta Telecommunications Research Centre v. Rambus, Inc., No. C06-

02595RMW, 2007 WL 4170564 *1 (N.D. Cal., Nov. 19, 2007); Atmel Corp. v. Info. Storage

Devices Inc., No. C95-1987 FMS, 1998 WL 775115 *2 (N.D. Cal., Nov. 5, 1998).

In this case, plaintiff reportedly accuses some 200 Silicon Labs products of

infringement. In his infringement contentions, he divides the accused products into several

categories titled: “Audio,” “Video,” “Wireless,” “Voice,” “Interface ICs,” and “Modems and

DAAs,” (Erickson Decl., Ex. H). Plaintiff has served claim charts only as to sixteen products

which he claims are “representative” of the 200 that have been accused. The claim charts

further divide those sixteen products into the following categories: “Receivers,”

“Transmitters,” “Transceivers,” “TV Tuners,” “RF Processing (such as RF Synch),” “Voice

Products,” and “Precision Mixed Signal Microcontrollers.” (Id., Ex. I).

At this juncture, this court is not prepared to strike Bender’s contentions, and

defendant’s motion to strike is denied. Nonetheless, defendant’s alternate motion to compel is

granted because this court agrees that Bender’s infringement contentions fail to comply with

Patent L.R. 3-1. To begin, Bender has made no showing that his use of “representative” claim

charts is proper. Other than plaintiff’s bare assertion, there is nothing in the record presented

indicating, for example, that the sixteen products for which plaintiff provided claims charts

share common circuitry with the other accused products. Further muddying the waters is

plaintiff’s grouping of the accused products into rather broad and amorphous categories that, on

their face, do not appear to readily correspond to the labels used in his claims charts.

Additionally, plaintiff’s infringement contentions are impermissibly vague. Bender has

done more than merely parrot the claim language. But his claims charts provide generic

allegations that do not identify specific circuitry or components that reportedly correspond to

the claim limitations — or, at least, not in a manner that gives defendant fair notice as to where

the alleged infringing circuits are located. Instead, Bender simply repeats the same generic

descriptions and cuts-and-pastes them beside each element of every claim. And, as to some

claim elements, plaintiff’s claims charts are left entirely blank. (Erickson Decl., Ex. I). 

Plaintiff contends that defendant’s engineers should be able to not only understand the terms

used in his infringement contentions, but also readily locate the subject circuitry in Silicon

Labs’ accused products. He suggests that the next step in this case should be for defendant to

produce detailed schematics, asserting that he cannot provide more detailed infringement

contentions without them. Suffice to say that Bender (not defendant) bears the burden of

identifying specifically where each and every claim element is found within the accused

products. And, this court finds that plaintiff’s infringement contentions need to be much

improved before he can proceed.

2 This ruling is based upon the court-ordered case management deadlines. 

Plaintiff states that he is willing to stipulate to an extension of those deadlines. If the

presiding judge concludes that an extension is warranted, this court finds that plaintiff should

have 30 days in which to amend his infringement contentions.

4

Accordingly, Bender will be given until March 26, 20102

 in which to amend his

contentions to (a) demonstrate that “representative” products are accurate representations of the

hundreds of other accused products and (b) provide specific locations within defendant’s

products where the alleged infringement occurs. Although the court has declined to strike

plaintiff’s contentions at this time, plaintiff’s contentions may well be stricken in the future if

they continue to be insufficient.

SO ORDERED.
