Looking for a print or e-book on an agriculture or life science topic? Depending on the topic, you might need to search both our library catalogs. Each catalog contains a listing of different books available from the Medical Sciences Library (MSL catalog) and from the other libraries on campus (LibCat catalog).
The MSL catalog contains books and e-books related to veterinary medicine, biomedical sciences, and agriculture and life sciences.
The LibCat catalog contains agriculture and life science-related print and e-books, as well as all other subjects studied at A&M.
The U.S. Patent & Trademark Office (USPTO) has a classification system to help you locate patents.
First, check the USPTO's Class Schedule to locate the appropriate plant subclass: patentable plants fall under the PLT class. Plant patents are organized by plant type (such as grass or shrub) and may include subclasses for specific characteristics (such as color, stems, or flavor). For example, roses fall in the PLT/101 class.
You can then conduct a search in the USPTO's Patent Full-Text and Image Database (PatFT). For example, entering CCL/PLT/101 in the advanced search query screen searches for the Current US Classification Class (field code CCL) Subclass PLT/101, and will return a list of patents assigned to that class (in the case of our example, patents for roses). Individual plant patents start with the code "PP" followed by up to 5 numbers.
Full color copies of U.S. plant patents at available at the West Campus Library. Help with searching for patents is also available at the West Campus Library (appointments encouraged).
