In the Union Carbide documents

U.S. Patent Office is named in 18 Union Carbide documents dated 1909 to 1980 (3 as the source, 18 mentioned), from asbestos lawsuits over Union Carbide's Calidria asbestos. All are published in our collection.

Names in the documents

The spellings documents use for U.S. Patent Office, OCR misreadings included, so a search for any of them finds this page: US Patent Office.

Where this comes from

This page brings together every document in our library that names U.S. Patent Office, across collections. Titles and affiliations are taken from the documents themselves, and units and subsidiaries are grouped under the company they belong to.

This page is provided for general informational purposes and does not constitute legal advice. Every asbestos case turns on its own facts, exposure history, diagnosis, deadlines, available evidence, and applicable law. Reviewing this page does not create an attorney-client relationship.
