Hallador Energy Company (HNRG)

No patent on file prints this company’s names. 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.

A subsidiary’s patents are counted only where the list of subsidiaries filed with its annual report has been read, and a patent sold to it after it was granted is not read. PatentsView’s data are published under the Creative Commons Attribution 4.0 licence. PatentsView at the USPTO
