I. INTRODUCTION As Plaintiff CamelBak Products, LLC’s patents explain, “For some time people have recognized the need to stay hydrated.” (Doc. 64-1, p. 14). This need has created a market for well-designed, reusable water bottles. CamelBak and Defendant Zak Designs, Inc. are competitors in this market. CamelBak brought this case alleging Zak is infringing on its patents for water bottles and water bottle lids. The parties now ask the Court to construe certain terms that appear in the claims— the recitations at the end of a patent that define the scope of the invention—of CamelBak’s patents. The Court conducted a claim construction hearing on December 2, 2022. In advance of the hearing, the parties submitted a Joint Claim Construction and Prehearing Statement (Doc. 63) which identified 23 claim terms in dispute. Pursuant to Northern

District of California Patent Local Rule 4.3(c),1 the parties also identified the 10 most significant terms for the Court to construe during the claim construction stage of this case. The parties then briefed their proposed constructions of those 10 terms. See Docs. 64, 65, 69. The parties’ briefing included declarations and deposition testimony from CamelBak’s expert witness, Jim Goldman, and Zak’s expert, John Hamilton. There is no dispute that both Mr. Goldman and Mr. Hamilton, as experienced mechanical engineers, qualify as persons of ordinary skill in the art. At the hearing, the Court entertained oral argument and presentations on the disputed terms identified as most significant by the parties. After the hearing, the Court instructed the parties to submit supplemental briefing

on their proposed constructions of an additional disputed term, variations of the word “bias.” See Docs. 71, 73, 74. Having fully examined the patents, briefing, exhibits, expert opinions, and the parties’ oral arguments and presentations, the Court construes the disputed claim terms as stated below.

1 The parties consented to the Court’s adoption of the Northern District of California Patent Local Rules in this case. II. BACKGROUND CamelBak’s Amended Complaint (Doc. 61) alleges Zak is infringing on six of its patents which fall into two patent families (collectively, “the Asserted Patents”). Within the six Asserted Patents, CamelBak alleges Zak has infringed 75 claims. The Asserted Patents are as follows:

Family Patent Number Priority Date Drink Bottles 9,463,911 (“the ’911 patent”) Apr. 11, 2005 Leak-proof flip-top water bottles 10,676,255 (“the ’255 patent”) 9,782,028 (“the ’028 patent”) Drink Containers 9,820,595 (“the ’595 patent”) Jan. 21, 2009 Push-button flip-top water bottles 10,165,879 (“the ’879 patent”) 10,542,833 (“the ’833 patent”) The ’255 patent is a continuation of the ’911 patent, and their specifications—the figures and text in a patent that precede the claims—are nearly identical. Similarly, the ’595, ’879, and ’833 patents are continuations of the ’028 patent with near-identical specifications for each patent. Therefore, this Opinion cites only to the ’911 and ’028 specifications. However, certain of the disputed claim terms appear only in the continuation patents. The '911 patent (Doc. 64-1) describes, in part, a drink container with a removable cap and a fluid conduit (tube). The cap has a manually operated drink spout and valve that allow for a closed configuration, wherein the spout is stowed and the valve prevents liquid from flowing through the fluid conduit, and an ig ~ Fig.2 □ fl? ) . open configuration, wherein the spout is in a Soe Ke) AS 140 100 GG) WMS hos dispensing position and the valve allows liquid to flow _ | G A? Ry through the fluid conduit. The drink spout has a flexible |! fhe) | □□ lI | | cS | | | mouthpiece that opens when the user bites down on it, a] | oA | □□ 28 allowing the user to drink liquid. The cap also has an | | a | | 1 □□ air return assembly that allows air to flow into the drink =|, | Ks 2) | ue container when the drink spout is in the dispensing “| : 2 position but does not allow air to flow when the spout “24 is stowed. The '028 patent (Doc. 64-3) describes a drink container that is similar to the drink container described in the ’911 patent. The container includes, in part, the following : .

biting down; two catch structures that secure the mouthpiece in the stowed position until activated; and a user release mechanism that allows the user to activate and release the mouthpiece from its stowed configuration so the mouthpiece can move automatically to the dispensing configuration. III. LEGAL STANDARD

“Victory in an infringement suit requires a finding that the patent claim ‘covers the alleged infringer’s product or process,’ which in turn necessitates a determination of ‘what the words in the claim mean.’” Markman v. Westview Instruments, Inc., 517 U.S. 370, 372 (1996) (quoting H. Schwartz, Patent Law and Practice 1, 80 (2d ed.1995)). This determination of the meaning of claim terms, known as claim construction, “is exclusively within the province of the court.” Id. at 372. Claim terms are given “the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention.” Phillips v.
