8 Plaintiffs, FURTHER ORDER REGARDING 9 v. CLAIM CONSTRUCTION

10 O’KEEFFE’S, INC., ORDER REGARDING MOTION FOR LEAVE TO AMEND Defendant. 11

12 I. INTRODUCTION 13 Plaintiffs Ely Holdings Limited and Greenlite Glass Systems Inc. move for leave to file a 14 second amended complaint against Defendant O’Keeffe’s, Inc. d/b/a SaftiFirst (“Safti”). The 15 Court held a hearing on January 31, 2020 regarding that motion, as well as a third-party discovery 16 issue that will be addressed in a separate order. For the reasons discussed below, Plaintiffs’ 17 motion for leave to amend is GRANTED. In the interest of avoiding a motion to dismiss that 18 would lead at most to another round of amendment, Plaintiffs may file a third amended complaint 19 no later than February 14, 2020. This order also addresses an issue of claim construction that 20 required supplemental briefing, which is resolved in Plaintiffs’ favor as discussed below.1 21 II. FURTHER CLAIM CONSTRUCTION ORDER 22 The Court previously resolved most of the parties’ claim construction disputes but 23 requested supplemental briefing as to aspects of one claim. See generally Claim Construction 24 Order (dkt. 112).2 The parties dispute the meaning of language in claim 24 of U.S. Patent No. 25

26 1 The parties have consented to the jurisdiction of the undersigned magistrate judge for all purposes pursuant to 28 U.S.C. § 636(c). 27 2 Ely Holdings Ltd. v. O’Keeffe’s, Inc., No. 18-cv-06721-JCS, 2019 WL 6911667 (N.D. Cal. Dec. 1 7,694,475 (the “’475 patent”) reading “comprising a first layer of glass which is a structural 2 glass and a second layer of glass which is a fire rated glass.” Plaintiffs offer the following 3 construction:

4 Composed of (i) a multi-laminated glass sheet made up of two or more layers of glass capable of bearing at least some of the weight of an 5 applied load, and (ii) a multi-layered glass sheet made up of two or more layers of glass that has a transparent intumescent material 6 interspaced between at least two of the glass layers 7 Pls.’ Br. (dkt. 85) at 14. Safti proposes the following construction:

8 Composed of (i) a single or multi-laminated glass made up of two or more layers of glass designed to bear, and capable of bearing, the 9 weight of a specified minimum load, and (ii) a multi-layered glass made up of at least two end layers of glass enclosing and sandwiching 10 transparent intumescent material between each glass layer, which has been rated as fire resistant by a national recognized rating entity. 11 12 Def.’s Br. (dkt. 92) at 18. 13 The Court resolved in its previous order the parties’ differing constructions of “structural 14 glass,” whether “fire rated glass” must be rated by a testing authority, and whether the outer layers 15 of “fire rated glass” must be glass, but withheld a ruling on “the issue of whether fire-rated glass 16 may contain additional layers other than alternating glass and intumescent material” pending 17 supplemental submissions of evidence. Claim Construction Order at 13–14. 18 Plaintiffs’ expert Tim MacFarlane states in his report that fire-rated glass consists of “a 19 multi-layered glass sheet made up of two or more layers of glass having an intumescent material 20 dispersed between at least two of the layers,” but does not specifically address whether fire-rated 21 glass may have additional layers not separated by intumescent material. See MacFarlane Opening 22 Report (dkt. 85-2) ¶¶ 120–27. Safti’s expert Dr. Glen Stevick states that “the second layer of 23 glass, which is a fire rated glass, . . . is meant to describe a multilayered glass made up of at least 24 two enclosing glass layers sandwiching transparent intumescent material,” and that a person 25 skilled in the art “would have interpreted the term ‘fire rated glass’ to be glazing whose interior 26 portion would be fire resistive layers with glazing at least on the two outer dimensions, with or 27 without glazing on the interior of the glazing.” Stevick Opening Report (dkt. 85-24) ¶¶ 34, 35 1 rated glass products referenced in the specifications of the patent. Safti’s evidence consists of 2 product brochures depicting, for the most part, configurations consistent with its expert’s view that 3 the fire-rated glass must be made up of alternating layers of glass and intumescent material, 4 although one product not specifically mentioned in the patent (Contraflam IGU, described as an 5 “insulated glass unit”) includes an aluminum spacer and empty space between two of its four 6 layers of glass (with the remaining layers separated by intumescent material), and the Court notes 7 that the “available options” for two such products (Contraflam Lite 60 and Contraflam 30) include 8 “Double glazing” and “Triple glazing,” which could perhaps take different configurations. See 9 Def.’s Supp’l Exs. 1, 4, 5 (dkt. 126). Plaintiffs submit brochures for products that include some 10 glass layers separated by spacers and air in addition to glass layers separated by intumescent 11 material, including Contraflam CF 120-N2, Pls.’ Supp’l Ex. A (dkt. 128); Climaplus Contraflam 12 CF A60-N2, id. Ex. B; Climaplus Contraflam CF Lite ISO, id. Ex. E; Climaplus Contraflam CF 13 Lite Marine ISO, id. Ex. H; Climaplus Contraflam CF 30-N2 ISO, id. Ex. I; Climaplus Contraflam 14 CF 60-N2 ISO, id. Ex. L; and Climaplus Contraflam CF 90-N2 ISO, id. Ex. N. While Plaintiffs 15 do not claim that any of those products are the particular products or configurations identified in 16 the specifications of the ’475 patent, they are in the same product families as the “Contraflam-N2” 17 and “Contraflam Lite” products mentioned therein, and the specifications make clear that the 18 products identified are not intended to be exclusive. See ’475 Patent at 2:14–18 (listing 19 “[p]articularly suitable fire rated glass” products and noting that “other fire rated glasses can be 20 used depending on their fire rating properties”); id. at 5:40–43, 6:18–19, 6:59–61,7:43–44, 8:15– 21 17 (identifying suitable products for certain embodiments of the patent). 22 A portion of the manufacturer’s website offered by Safti describes the Contraflam product 23 family as “a single- or multi-chamber fire-resistant glass containing an environmentally friend 24 intumescent interlayer,” and states that it is “[a]vailable as butt-joint, laminated and insulated 25 glazing. Def.’s Supp’l Ex. 2. In the absence of evidence to the contrary, the Court understands 26 that description as including “insulated” products like the Contraflam IGU—which includes an air 27 space rather than intumescent material between two of its four layers of glass—within the 1 term “fire rated glass” in the ’475 patent. This evidence weighs against Safti’s proposed 2 construction requiring intumescent material separating all layers of glass. With no evidence that 3 “fire rated glass” must have intumescent material between all layers of glass, and at least some 4 evidence that other configurations have been marketed as “fire-resistant glass,” the Court adopts 5 Plaintiffs’ proposed construction of this claim term. 6 Based on that holding as well as the issues addressed in the Court’s previous claim 7 construction order, the Court construes the language in claim 24 reading “comprising a first layer 8 of glass which is a structural glass and a second layer of glass which is a fire rated glass” as 9 follows:

10 Composed of:

11 (i) a laminated glass sheet made up of two or more layers of glass capable of bearing weight; and 12 (ii) a multi-layered glass sheet meeting all of the following 13 conditions:

14 a. made up of two or more layers of glass;

15 b.
