McLeland, Le-Nhung, American Chemical Society, 2001

"This database makes searchable the copyright renewal records received by the US Copyright Office between 1950 and 1992 for books published in the US between 1923 and 1963. Note that the database includes ONLY US Class A (book) renewals."

Each month, the USPTO seeks to inspire and encourage innovation by sharing relatable stories that chronicle the journeys of inventors and entrepreneurs. We shed light on where they got their start, the challenges they faced, and what it took to bring their ideas to fruition and their brands to life. The stories also emphasize the importance of creating and protecting intellectual property, and the critical role it plays in innovation. The full roster of content can be searched here.
