Opinion

□ USDC SDNY □ UNITED STATES DISTRICT COURT DOCUMENT SOUTHERN DISTRICT OF NEW YORK ELECTRONICALLY FILED x POC Bee | DATE FILED: [/3 GEIGTECH EAST BAY LLC, | anmne encamced Plaintiff, 18 Civ. 05290 (CM) -against- 19 Civ. 04693 (CM) 20 Civ. 10195 (CM) LUTRON ELECTRONICS CO.,, INC., Defendant. SECOND CLAIM CONSTRUCTION DECISION McMahon, J.: The court issued its original claim construction decision on May 5, 2022, (Dkt. No. 163). However, it became apparent some months ago that the parties did not agree on the meaning of two additional terms — “adjacent” and “extends away” — as used in the ‘717 patent. Since the parties’ experts rely on opposing definitions of these terms, claim construction will also determine whether I will allow or disallow certain expert testimony related to these two disputed terms, L Relevant Procedural History The court assumes the parties’ familiarity with the facts and the procedural history of the □ case, An extensive discussion of both is available in the court’s August 12, 2021, Decision and Order Denying Plaintiff's Motion for Preliminary Injunction and Staying the Remainder of the Case, (Dkt. No. 141), and May 5, 2022, Claim Construction Decision. (Dkt. No. 163). However, in order to understand fully the parties’ claim construction arguments, it will be necessary to recount some of it yet again.

A. The Dispute Over “Adjacent” On December 22, 2022, Lutron’s technical expert, Dr. Eric Maslen, issued his noninfringement report. (Dkt. No. 218-2). The court’s claim construction decision — construing all terms that the parties had identified as disputed — had already issued. The court, and I assume the parties, were under the impression that no other terms remained to be construed. Unfortunately, Maslen’s report revealed that GeigTech and Lutron assigned different meanings to two additional terms. The parties’ first dispute is over the meaning of the term “adjacent” as it is used in element 8[c] of the ‘717 Patents’ claims. The claim element describes, “an opening extending through the bracket, the opening having a first end adjacent the first surface and a second end adjacent the second surface ... .” (emphasis added). Maslen explains that he “understand[s] the ordinary □

meaning of ‘adjacent? may imply touching or adjoining, or it could mean something more subjective such as being near to.” (Dkt. No. 218-2 9197). In the context of element 8{c], Maslen interprets “adjacent” to mean “adjoining.” Based on this definition, Maslen argues noninfringement, since the Palladiom system’s “‘second end’ does not touch (or adjoin) the identified ‘second surface.’” (Dkt. No. 218-2 4197) (emphasis added). On February 23, 2023, GeigTech’s noninfringement and invalidity expert, Dr. Nancy Perkins, testified during her deposition that for the purpose of her infringement analysis “adjacent” means “nearby.” (Dkt. No. 277, 17). On February 24, 2023, in a Motion in Limine to Exclude the Testimony of Maslen, GeigTech argued that the court should exclude Maslen’s infringement opinions, on the ground that he had not applied the proper construction of the “adjacent” limitation. (Dkt. No. 216). In its opposition, Lutron argued that GeigTech was the party improperly construing the term because,

while GeigTech did not offer a definition for “adjacent,” its expert, Perkins, had misconstrued “adjacent” during her deposition to mean “nearby.” (Dkt. No. 277, 17). On September 20, 2023, I issued a decision and order on multiple motions to strike, motions to exclude the opinions and proposed testimony of multiple experts, and motions for

summary judgment. (Dkt. No. 308). In that decision, I opined on the “adjacent” issue: While GeigTech is correct that there is no reason Lutron could not have raised these claim construction issues earlier, it seems clear to me that neither side understood that the other was interpreting the term “adjacent” differently. ... The question then is whether “adjacent” truly has more than one ordinary meaning or whether one expert is operating with an etroneous understanding of the term’s meaning, Upon review, it is apparent that the term “adjacent” has more than one ordinary meaning. ft can mean adjoining or abutting, or it can mean close to, without necessarily touching. The question is what the term means in the context of this patent. That requires claim construction. (Dkt. No. 308, 64-65). B. The Dispute Over “Extends Away” Maslen’s noninfringement report gives rise to a second disputed claim term. Maslen argues noninfringement of element 1 [a] of the ‘717 Patent Claims, which describes “a side configured to bear against the support surface such that the bracket extends away from the support surface and is adjacent an end of the roller window shade assembly.” (emphasis added). Maslen claims that, because the Palladiom bracket has a foot, “[o]nly a portion of the bracket extends away from the support surface,” and another portion of the Palladiom bracket (.e., the “foot” portion) extends parallel to the support surface. (Dkt. No, 218-2 §{145-151) (emphasis added). Thus, Maslen concludes that the Palladiom brackets do not infringe, since the entire bracket does not extend

away from the support surface. GeigTech’s Second Motion for Summary Judgment disputed Maslen’s interpretation as improperly narrow. GeigTech also argued that Lutron had waived any right it might have had to

propose “new” constructions of “extends away.” (Dkt. No. 239, 7-9). GeigTech did not offer its

own proposed constructions for these terms, which suggests that it assigns the phrase its ordinary meaning. Id. Once again, it was apparent that the parties disagreed about the meaning of terms that had not previously been identified as contested. Accordingly, I asked for additional claim construction briefing on “extends away.” When I ordered additional briefing, I informed the parties that I would not follow my usual rule that claim construction arguments be limited to intrinsic evidence in the first instance. I ordered that the parties should first argue that intrinsic evidence supports their proposed construction, and then argue that extrinsic evidence (which could include testimony from persons skilled in the art) does so. As the Federal Circuit requires, I will rule based on intrinsic evidence if I can, and resort to consideration of extrinsic evidence only if I cannot. Once these disputed claims are construed, I will also make a final ruling about whether any of the proposed expert testimony about “adjacent” or “extending away” will be allowed or excluded. II. Legal Standard In interpreting disputed patent claims, the court looks first to the intrinsic evidence of record — the patent itself, the claim language, the specification, and the prosecution history, if in evidence. Liquid Dynamics Corp. v. Vaughan Co., Inc., 355 F. 3d 1361, 1367 (Fed. Cir. 2004). The specification is always highly relevant to claim construction analysis. The Federal Circuit has indicated that the specification is “the single best guide to the meaning of a disputed term,” (Phillips v. AWH Corp., 415 F. 3d 1303, 1315 (Fed. Cire. 2005) (en banc)), and the Supreme

Court has held that claims are to be construed “in light of the specifications and both are to be read with a view to ascertaining the invention.” United States v, Adams, 383 U.S. 39, 39 (1966). Claim construction is a straightforward process. Markman v. Westview Instruments, Inc., 517 U.S. 370, 372 (1996). The words of a claim are generally given their ordinary and customary meaning, Phillips, 415 F.3d at 1313.
