Series IV. Patent Files, 1955-2012

Arranged alphabetically by subject, this series contains Lloyd H. Conover's patent files. These files pertain to inventions conceived and developed by Conover for Pfizer, Incorporated and its corporate predecessor Charles Pfizer & Company, Incorporated. The materials in the Patent Files contain technical information for the represented inventions. To a very limited extent, they also provide information regarding legal issues associated with Conover's patents. From the Patent Files, one can also gain insights into the conception, research, and development work involved in bringing the represented inventions into being.

The contents of the Patent Files consist mainly of printed copies of patents and photocopied patents. A small amount of correspondence, photocopied certificates of correction, patent lists, and magazine articles are also found in this series. A publication, a paper manuscript, and a CD-ROM (featuring a digital image of the original tetracycline patent) are preserved here as well.
