Opinion

ORDER GRANTING DEFENDANTS’ MOTION FOR SUMMARY JUDGMENT AS TO NONINFRINGEMENT AND INVALIDITY BASED ON INDEFINITENESS; DENYING OTHER MOTIONS AS MOOT

SUSAN ILLSTON, District Judge.

On November 14, 2008, the Court heard argument on various motions for summary judgment filed by defendants. For the reasons set forth below, the Court GRANTS defendants’ motion as to noninfringement and invalidity based on indefiniteness. In light of the Court’s resolution of that motion, the Court DENIES AS MOOT defendants’ motion to amend the answer, and defendants’ other motions for summary judgment.

BACKGROUND

The '025 patent, titled “Apparatus and Method for Interactive Communication for Tracking and Viewing Data,” issued from a “continuation” patent application of an earlier application filed in October of 1993. The patent is generally directed to use of an information processing system for acquiring and displaying information, and describes and claims methods for acquiring and displaying real estate and property-related information (Claims 1 and 3) and a related system for tracking such information (Claim 5). Pleune Decl. Ex. 1 ('025 patent).

Plaintiffs filed suit in 2003, alleging that numerous websites operated by defendant Homestore.com (now Move, Inc.) (“Move”), infringe claims of the '025 patent. Defendant’s websites are devoted almost entirely to home and real estate-related content, and include www.realtor.com, www.move. com, www.homestore.com, www. homebuilder.com, www.rentnet.com, www. springstreet.com, and www.seniorhousing net.net. Mahnken Decl. ¶ 2. Plaintiffs have also sued the National Association of Realtors (“NAR”) and the National Association of Homebuilders of the United States (“NAHB”) by virtue of their involvement with Move in the www.realtor.com and www.homebuilder.com websites, respectively.

After this suit was filed, defendants instituted an ex parte reexamination of the '025 patent, submitting prior art that they believed showed that the PTO should never have issued the '025 patent. The PTO initially disallowed claims 1-5, but after receiving further written comments from plaintiff Keithley, on March 20, 2007, the PTO issued a reexamination certificate that confirmed the patentability of original claims 1-9 without amendment and deemed new dependent claims 10-15 to also be patentable over the prior art. Pleune Decl. Ex. 2. In an order filed September 10, 2007, Judge Jenkins construed 10 terms taken from Claims 1, 3 and 5.

DISCUSSION

Defendants have moved for summary judgment of noninfringement as to Claims 1 and 3, and invalidity based on indefiniteness as to Claim 5.

*980 A. Claim 1

Claim 1 provides, in its entirety:

1. A method of acquiring and displaying real estate information utilizing an information processing system containing file server means for serving files, said file server means having i/o means for receiving and transmitting data, and database storage means for storing information in database files, the method comprising the steps of:
a) receiving real estate related information;
b) storing digitized real estate data and related information as information records in said database storage means of said file server means in a manner in which data can be selectively accessed;
c) receiving digital electronic first end user information from a first end user relating to said first end user’s real estate needs;
d) selectively providing digital electronic information of portions of said real estate data based on said digital electronic end user information;
e) accessing data files by said first end users, said accessing data files by said first end users being a plurality of inquiries from individual first end users, said end user inquiries being the retrieving and viewing of text and/or graphic data from a database;
f) generating a demographics information database by compiling and merging a plurality of first end user inquiries and storing said compiled and merged inquiries; and
g) providing a second end user with said demographic information, said demographics information corresponding to the specific text and graphic data selected from said database files by said first end users.

'025 patent col. 14,11. 34-65.

Defendants contend that step (e) of method Claim 1 describes, at least in part, an action to be taken by first end users acting independently in accessing the system. Defendants argue that “accessing data files by said first end users” means that first end users access data files, and that because this clause requires action by other parties, defendants can only be held liable if plaintiffs can show that the circumstances meet the requirements for a finding of joint infringement. Plaintiffs respond that Judge Jenkins’ claim construction of step (e) requires a finding that this step, in its entirety, relates only to the system passively collecting data, and therefore does not require any action by first end users.

In construing step (e) of Claim 1, Judge Jenkins did not construe “accessing data files by said first end users.” Judge Jenkins did construe the final clause in step (e) — “said end user inquiries being the retrieving and viewing of text and/or graphic data from a database” — to mean “said end user inquiries being requests for information that are passively monitored.” Claim Construction Order at 5-8, 36. Plaintiffs rely on the following language from the Claim Construction Order:

In reviewing the current record, the Court finds [the inventor’s] statements during the '025 Patent prosecution reexamination history to be compelling evidence in support of Plaintiffs’ proposed construction. Plaintiffs’ proposed construction incorporates the term “passively monitored.” To that end, it is undisputed that Keithley consistently explained in March 2005, and again in April 2005, that Claim 1(e) relates only to the system “passively” collecting data by watching the end user, rather than *981 requiring the end user to respond to questions. Because the prosecution history is compelling and because Defendants’ arguments to the contrary lack merit, the Court finds that the prosecution history weighs heavily in favor of Plaintiffs’ proposed construction.

Order at 7-8.

Defendants respond that Judge Jenkins was only construing, and thus only discussing, the final clause in step 1(e) in its order and in no way indicated that the initial clause in 1(e) did not require action by first end users. Defendants argue that Judge Jenkins was distinguishing between “active” and “passive” monitoring of the first end users’ actions when accessing data files (“Keithley’s express clarification that the claim term at issue [the final clause of 1(e) ] focuses on ‘watching the actions of the end user’ and monitoring ‘the behavior of the first end user as they surf through the database.’” Id.
