MEMS gyroscopes are currently a very hot business. Investigating the patent situation is essential to understanding the present business climate and anticipating future developments.

The MEMS gyroscope patent landscape is heating up!

The gyroscope market is driven by mobile applications, where until recently only two players, STMicroelectronics (ST) and InvenSense, were competing. Now, many companies are present. The first patent disputes to develop over the last few years (linked to Wacoh's patents) or that are currently occurring (ST vs. InvenSense) signal the beginning of a fight for gyro and inertial combo market ownership.

This report represents a link to the technical trends Yole Développement has observed in the industry. Comparisons and matching between existing product process flows (reconstituted from teardowns) and related patents are provided. In particular, a case study on InvenSense's MPU-9150 9-axis sensor is included.

As illustrated by the aforementioned disputes, (which are detailed in this report), IP is critical in this area; thus, the link between IP and market evolution is critical as well. One of this report's most important findings READ MORE >
