content: Series 2: Invention & Patent Materials (1915-1967) consists of invention records that include original concept drawings, legal records and patents, marketing correspondence, and the business records of Friedman's sole proprietorship invention business, the Commercial Research Company.  It is important for researchers to note that information on the assignment of straw patents and their machinery, all associated legal records to those specific issues, as well as patent defense case research, and straw advertising and marketing after 1938 may be found in Series 3.  Series 2 is divided into several subseries.  Subseries 2.1 to 2.13 are patented inventions arranged chronologically by patent issue date, and include research and development, legal records and correspondence, and advertising and marketing materials.  They also contain unpatented inventions and  business records, as well as multiple concept drawings and invention lists that refer to both patented and unpatented inventions.  Researchers interested in the conceptual development of the straw should review the information contained not only in Subseries 2.5: Drinking Tube and Subseries 2.8: Flexible Straw, but also in Subseries 2.12: Invention Lists & Drawings for straw ideas that were drawn on lists or sketches with other concepts.  Additionally, researchers interested in the manufacturing device for the straw should review Subseries 2.9: Apparatus & Method for Forming Corrugations in Tubing, as well as Subseries 2.11: Unpatented Inventions, for the Flexible Straw & Method of Forming Same information.
