A patent is counted where the owner printed on it when it was granted carries the company’s own name, a former name, the name of a subsidiary its annual report lists, or its own name with a patent-holding phrase (Technology Licensing, Intellectual Property and the like), once the legal form, case and punctuation are set aside, and prints a country that name counts in.
