13 Plaintiff, FINDINGS AND RECOMMENDATIONS REGARDING 14 v. CLAIM CONSTRUCTION

15 WHIPPLE INDUSTRIES, INC, doing business (ECF Nos. 40, 44, 45, 47, 48) 16 as Whipple Superchargers,

17 Defendant.

19 I. INTRODUCTION 20 Plaintiff Edelbrock, LLC (“Edelbrock”) filed this action against Defendant Whipple 21 Industries, Inc. doing business as Whipple Superchargers (“Whipple”) alleging infringement of 22 United States Patent No. 9,683,481 (the “‘481 Patent”), pursuant to the United States Patent Act, 23 35 U.S.C. § 1 et seq. (ECF No. 1.) 24 This matter is before the Court on the parties’ competing briefs regarding claim 25 construction of five terms in the ‘481 Patent. (ECF No. 40.) The parties filed their principal claim 26 construction briefs on September 11, 2020, and their responsive claim construction briefs on 27 October 1, 2020. (ECF Nos. 44-45, 47-38.) The Court held a claim construction hearing on 1 relevant documents, as well as the parties’ arguments at the hearing, and recommends construing the disputed claims as set forth below. 2 II. BACKGROUND 3 The ‘481 Patent is titled “Dual Pass Intercooled Supercharger.” (ECF No. 44-2 at 2.) Chad 4 Magana and Robert Simons are the inventors and Edelbrock is the applicant and assignee. (Id.) 5 Edelbrock filed its patent application on March 22, 2016, and the ‘481 Patent was issued on June 6 20, 2017. (Id.; ECF No. 45-6 at 2-10.) 7 The ‘481 Patent is “directed to a dual pass intercooled supercharger and method of 8 compressing and cooling air to an engine intake.” (ECF No. 1 at 3.) The dual pass intercooled 9 supercharger is described as “including a supercharger; and an intercooler in fluid communication 10 with an exit of the supercharger, the intercooler configured as a dual pass heat exchanger.” (ECF 11 No. 44-2 at 10.) A dual pass heat exchanger “is defined as a heat exchanger where the fluid 12 passing through the exchanger passes through the heat exchanger more than once.” (Id. at 12.) Air 13 is compressed in a supercharger and then passed through “a first portion of an intercooler in fluid 14 communication with an exit of the supercharger[.]” (Id. at 10.) The air then exits the intercooler 15 into a common chamber and is passed through a second portion of the intercooler different from 16 the first portion. (Id..) “A heat exchange medium” such as water or coolant “may be in fluid 17 communication between the first portion and the second portion of the heat exchanger.” (Id.) The 18 supercharger and intercooler “may be integrated into a single housing or may be separate.” (Id. at 19 12.) 20 /// /// 21 /// 22 /// 23 /// 24 /// 25 /// 26 /// 27 /// 1 30 2 36b 50 36a 36 48

In this exemplary embodiment, a housing [32] encloses and directs air from 14 | the supercharger chambers [34] to the intercooler [36] and out the runners [40] to the engine. (/d.) 15 | The supercharger compresses the air, which enters the central chamber [48] toward the 16 || intercooler [36]. Ud.)

Seals [60] divide the heat exchanger 19 into first and second portions to permit the dual pass through the heat exchanger. (/d. at 12.)

1 On October 27, 2017, Whipple petitioned the United States Patent and Trademark Office (“USPTO”) for an ex parte reexamination of the ‘481 Patent. (ECF No. 48-9.) Whipple requested 2 reexamination based upon a YouTube video and an associated declaration, U.S. Pre-grant 3 Publication 2010/0108040 to Simons et al., WO 2015/179048 to Callaway et al. (“Callaway”), 4 and U.S. Pat. No. 7,213,639 to Daniellson et al. (Id.) The USPTO accepted the request to 5 reexamine the ‘481 Patent and Edelbrock submitted a response. (ECF No. 45-7 at 46-79.) The 6 USPTO subsequently issued a final rejection. (ECF No. 48-10.) Edelbrock requested 7 reconsideration on November 5, 2018 and submitted claim amendments and supporting 8 arguments. (ECF No. 48-11.) The USPTO found the amended claims patentable and issued a 9 reexamination certificate on January 15, 2019. (ECF No. 48-12; ECF No. 44-5.)1 10 Edelbrock filed this action on October 23, 2019, alleging violations of claims 1 and 17 of 11 the ‘481 Patent and seeking a permanent injunction, lost profit damages, and a finding of willful 12 patent infringement. (ECF No. 1.) The parties agreed to constructions for three terms in claims 1 13 and 17 of the ‘481 Patent while five terms or phrases remain in dispute. (ECF No. 40.) 14 III. LEGAL STANDARDS 15 A. Key Patent Concepts 16 A patent must “describe the exact scope of an invention and its manufacture to secure to 17 the patentee all to which he is entitled and to apprise the public of what is still open to them.” See 18 Markman v. Westview Instruments, Inc., 517 U.S. 370, 373 (1996). A patent application must 19 contain a “specification” and at least one drawing. 35 U.S.C. § 111. There are two distinct parts 20 of a patent specification. The first is a detailed “written description of the invention and of the manner and process of making and using it,” set forth “in such full, clear, concise, and exact 21 terms as to enable any person skilled in the art . . . to make and use the same.” 35 U.S.C. § 112(a).
