UNITED STATES DISTRICT COURT NORTHERN DISTRICT OF OHIO EASTERN DIVISION

VANOCUR REFRACTORIES, LLC, ) CASE NO.: 1:23-cv-2162 ) Plaintiff, ) JUDGE BRIDGET MEEHAN BRENNAN ) v. ) ) FOSBEL, INC., et al., ) MEMORANDUM OPINION ) AND ORDER Defendants. )

Before the Court is Defendant Fosbel, Inc.’s (“Fosbel”) Motion to Dismiss the Amended Complaint. (Doc. 60.) The motion is fully briefed. (Docs. 66, 68.) For the reasons stated herein, Fosbel’s Motion to Dismiss is DENIED in part and GRANTED in part. I. BACKGROUND A. Factual Background A coke oven is used to heat coal to extremely high temperatures. (Doc. 57 at ¶ 37.) The heating process creates coke suitable for use in the steel industry. (Id.) Some coke ovens include a feature called corbels. (Id. at ¶ 38.) A corbel is a structure of stacked bricks or blocks that not only support the heating walls but also channel air, gas, and exhaust heat. (Id.) Plaintiff Vanocur Refractories, LLC (“Vanocur”) invented technology to use refractory blocks (which are longer and larger than bricks) to create or replace corbels. (Id. at ¶¶ 45-48.) Vanocur refers to its technology as “Big BLOCK Solutions” design and Modular Cast Block (“MCB”) technology. (Doc. 57 at ¶¶ 1, 37.) This technology allows Vanocur to more quickly and efficiently manufacture, repair, or replace corbels in a coke oven. (See id. at ¶¶ 38-48.) At issue in this case is U.S. Patent No. 8,266,853 (“the ’853 patent”). (Id. at ¶ 49; see also Doc. 57-1.) It relates to the products and methods used to repair or replace corbels in a coke oven. The ‘853 patent includes nineteen claims, two of which are at issue in this case. (Doc. 57 at ¶ 51.) Claim No. 1 is an independent claim that recites a particular design of corbel using two tiers of modular blocks with particular apertures that form three passageways for gas. (Id.) The invention claimed is: 1. A corbel comprising:

a first tier having first blocks, each of the first blocks comprising a first, substantially horizontal aperture extending through the first block from a front surface to a back surface and a second, substantially vertical aperture formed through atop surface of the block, extending into the first aperture, the first blocks being arranged on a substantially planar surface to align the respective first apertures to define a first, substantially horizontal passageway, a second tier having second blocks, each of the second blocks comprising a third, substantially vertical aperture extending through the second block from a top surface to a bottom surface, the second blocks being disposed above the first tier of blocks to align the third aperture of each of the second blocks with the second aperture of the first blocks to form a second passageway; a third passageway extending diagonally from the top of the one of the second blocks to a side of at least one of the first and second blocks; and a gas source for providing gas to the first passageway. (Doc. 57-1 at 1645.)1 Claim No. 10 is a dependent claim that recites a method of constructing the corbel in Claim 1. (Doc. 57 at ¶ 51.) 10. A method of constructing the corbel of claim 1, comprising the steps of: laying the first tier of blocks; laying the second tier of blocks above the first tier of blocks; and

(Doc. 57-1 at 1646.) Vanocur alleges it contracted with a customer Stelco, Inc. (“Stelco”), a North American corporation, for the design and production of a coke oven that used the “Big BLOCK Solution” design. (Doc. 57 at ¶ 8.) At some point in 2020, Stelco halted Vanocur’s work on the coke oven. (Id. at ¶¶ 11-12.) Vanocur alleges Stelco contracted with Fosbel to fill its remaining coke oven repair needs. (Id. at ¶¶ 18-19.) According to Vanocur, Fosbel misrepresented that Vanocur’s patent had expired, which would mean Fosbel could use Vanocur’s patented

technology and design. (See id.) Vanocur alleges Fosbel directed subcontractors, including Upstate Refractory Services, Inc. (“Upstate”), to manufacture refractory blocks that infringe on the ‘853 patent. (Id. at ¶¶ 77- 79.) Vanocur alleges these blocks were given to Fosbel. (Id. at ¶ 79.) Fosbel then assembled, kept, and/or provided the blocks to Fosbel in Brook Park, Ohio; USX Clairton in Clairton, Pennsylvania; and Stelco in Ontario, Canada. (Id.) Vanocur alleges it became aware of this potential infringement after viewing Upstate’s website, which included photographs of these blocks that “looked remarkably similar to Vanocur’s patented refractory-brock corbel design.” (Id. at ¶ 96.) The Amended Complaint includes photographs of modular blocks located at different

locations within the United States. (See id. at ¶¶ 107-28.) These locations belong to Fosbel suppliers directed by Fosbel. (See id.) Vanocur alleges those blocks are specifically designed to mimic the blocks used in the ‘853 patented design. (Id. at ¶ 125.) The specially designed blocks have no non-infringing use. (Id. at ¶ 126.) B. Procedural History In April 2022, Vanocur initiated a lawsuit against Fosbel, Stelco, and Upstate for infringing on the ‘853 patent. (Id. at ¶ 95.) After Vanocur initiated this lawsuit, Stelco agreed to let Vanocur conduct a site inspection of its coke oven. (Id. at ¶ 97.) Following this visit, Vanocur voluntarily dismissed the suit without prejudice. (Id. at ¶¶ 97-102.) Vanocur claims

that since dismissing that suit, it learned that Fosbel was storing potentially infringing refractory blocks in Clairton, Pennsylvania and Brook Park, Ohio, in addition to Stelco’s site in Ontario, Canada. (Id. at ¶ 102). The Amended Complaint alleges some of the blocks were supplied to Stelco in Canada. (See id.) Moreover, the blocks “have distinct characteristics that necessarily infringe on plaintiff’s ‘853 patent.” (Id. at ¶ 103.) On September 7, 2023, Vanocur filed its complaint in the Western District of New York. (Doc. 1) On October 31, 2023, the parties stipulated to transfer venue to this Court. (Doc. 9.) Vanocur’s original complaint contained two counts. In Count One, Vanocur claims infringement of the ‘853 Patent under the component export provisions of 35 U.S.C. §§ 271(f)(1) and (2). (Doc. 1 at 42-45, ¶¶ 129-43.) In Count Two, Vanocur alleges “literal” (typically

referred to as direct) infringement under 35 U.S.C. § 271(a). (Id. at 45-47, ¶¶ 144-54.) On December 21, 2023, Fosbel filed a motion to dismiss as well as a motion to stay proceedings. (Docs. 25, 26.) On August 30, 2024, Vanocur sought leave to file an amended complaint to add Ceramic Holdings Inc. (“Ceramic Holdings”) as a defendant, which was granted. (Docs. 46, 56.) On October 28, 2024, Vanocur filed its Amended Complaint. (Doc. 57.) The Amended Complaint alleges: Defendant, Fosbel Inc., is an engineering company that specializes in refractory repairs, and maintenance in the steel, coke, and glass markets. Defendant Ceramic Holdings practiced the same business before selling its assets relating to that business to Fosbel. As such, to avoid confusion, unless otherwise noted, “Defendants” herein refers to the continuous coke-oven-related business operating as Ceramic holdings before the asset purchase and then Fosbel after. (Doc. 57 at ¶ 2.) The Amended Complaint also quotes Fosbel’s Initial Noninfringement Contentions. (Id.
