Patents

Several national governments have a means to protect inventions by excluding others from making, using or selling it for a set period of time. This is called a patent and is issued by a patent office. In order for a patent to be granted, the invention must meet several criteria, some of which include “newness”, utility and not something that would be obvious to someone working in the field.

The following table presents the US patent number and a brief description of the patent associated with Endevco. These range from accelerometers to pressure sensors to electronic assemblies to systems. Note: The patents are either Endevco’s or those granted using an Endevco part in the testing process to design the product.
