I'll verify the company's profile with web searches.
Let me verify the litigation context and confirm ownership/size details.
Company overview. IKO Industries Ltd. (commonly "IKO") is a private, family-owned manufacturer of roofing, waterproofing, and insulation products. The modern business was founded in 1951 in Calgary, Alberta by Isidore Koschitzky (the corporate group traces its origins to a 1905 German plant). Its North American headquarters are listed at 40 Hansen Road South, Brampton, Ontario; some directories also cite Calgary. As a private company it files no public financials, so revenue and headcount are third-party estimates only — commonly cited bands range from roughly 1,000–5,000 employees and several hundred million to under $1 billion in revenue. Parent ownership is the Koschitzky family; no public ticker.
Products / services. IKO manufactures and sells building-envelope materials: residential asphalt shingles, synthetic roofing underlayments, modified-bitumen and built-up commercial roofing membranes, single-ply TPO membrane, waterproofing and air/vapor barrier systems, and polyisocyanurate and expanded-polystyrene insulation. It operates as a vertically integrated producer (processing its own asphalt, granules, and glass mat) across more than 30 plants in North America, Europe, Asia, Israel, and New Zealand, selling in roughly 96 countries.
Patent-litigation posture. The case data shows IKO as a defendant in a single tracked suit — zero plaintiff filings — the classic profile of an operating company defending against a patent assertion, not an NPE. The suit was filed by Kirsch Research & Development, LLC, characterized in court records and docket metadata as an NPE (Simi Valley, California) asserting acquired underlayment patents.
Notable case. Kirsch Research & Development, LLC v. IKO Industries, Inc. et al., No. 6:20-cv-00317-ADA (W.D. Tex., Waco Division), filed April 24, 2020, asserted U.S. Patent 6,308,482 ("Reinforced Roof Underlayment") against IKO's synthetic underlayments. Kirsch filed the same day as part of a wave of ~16 complaints against roofing/underlayment makers (Owens Corning, GAF, Atlas, Intertape, and others), plus an ITC action; several defendants, including IKO, petitioned for inter partes review. The Waco Division is a plaintiff-favored patent venue. The tracked case closed October 5, 2021, and PTAB proceedings ultimately cancelled all claims of the '482 patent.
Kirsch asserted the '482 patent against IKO. A claim-construction order issued in 2021, and the case was stayed pending IPR; related IPR2022-00416 was denied institution on 2022-05-20.
