System Components Corporation

Company overview. System Components Corporation is a privately held manufacturer of synthetic roofing underlayments based in Issaquah, Washington (PO Box 2432 / 50 SE Bush St.), operating the website systemcomponents.net. Washington state corporate records list a "System Components Corporation" registered in 2003 with that Issaquah address and a mailing address in Hudson, Ohio — the latter consistent with the Ohio venue of the litigation below. The company is not publicly traded and no public source verified here confirms its employee count, revenue band, parent ownership, or founding year; it should not be confused with similarly named firms such as System Components, Inc. of South Haven, Michigan (power-transmission couplings) or System Components of Farmers Branch, Texas.

Products / operations. The company makes mechanically fastened and self-adhered synthetic roof underlayments for sloped residential and commercial roofs — asphalt shingle, tile, metal, cedar shake and slate applications. Branded lines documented in ICC-ES evaluation reports (ESR-1293) and company literature include FelTex (cross-woven polypropylene scrim with a two-ply coating), FelTex SA300 (self-adhering, ice-barrier rated), CoverPro / CoverPro 1000, 2000 and 3000, ProtEx Contractor Grade, and QuickSilver (a mechanically fastened underlayment aimed at tile and metal systems). Products are sold through building-products distributors, and a 2005 U.S. customs ruling shows materials imported as roll goods.

Patent-litigation posture. System Components is an operating company, not an assertion entity. The tracked record shows one case and it is purely defensive: as defendant in Kirsch Research & Development, LLC v. System Components Corporation (N.D. Ohio, 5:20-cv-00903-DAP, filed April 24, 2020). Zero plaintiff-side cases. The plaintiff, Kirsch Research & Development, LLC of Simi Valley, California, is a non-practicing licensor that in 2020 filed a broad campaign of parallel suits against roofing-underlayment manufacturers and distributors nationwide (including Atlas Roofing, GAF, DuPont, TAMKO, CertainTeed, IKO, Tarco, BlueLinx and Epilay) plus an ITC Section 337 complaint (Inv. No. 337-TA-1202) asserting U.S. Patents 8,765,251 and the then-expired '482 patent.

Case context. The N.D. Ohio action was stayed (Dkt. 25) pending the parallel manufacturer litigation and PTAB proceedings, reflecting the customer/defendant-coordination dynamics typical of that campaign. No other litigation involving System Components Corporation appears in the tracked data.
