We hold patents and trademarks reflecting functional, design and technical accomplishments in a wide range of areas covering both basic production of certain aerospace products as well as highly specialized devices and advanced technology products in defense related and commercial fields.
Although the company's patents and trademarks enhance our competitive position, we believe that none of such patents or trademarks is singularly or as a group essential to our business as a whole. We hold or have applied for U.S. and foreign patents with expiration dates that range through the year 2027.
Registered trademarks of Kaman Corporation include KAflex®, KAron®, and K-MAX®. In all, we maintain 23 U.S. and foreign trademarks.
