It’s not strange for companies to go after each other’s patents, but usually the names of the two parties are known. In this particular case, however, we don’t know who is making a move against Apple. One theory is that Google is behind the filing, and it’s a legitimate theory. Apple has been using patents ‘381 and ‘949 to impose limitations on top Android manufacturers such as Samsung, Motorola, and HTC.
Not surprisingly, everyday there’s a new patent war, but as it stands, many tech giants need to carve out a stake in the “multitouch” department to keep their devices competitive. It’s unlikely that ‘949 will be an Apple’s exclusive in the future since it mainly deals with the tolerance level and angle of the initial touch movement on a touch interface.
As seen in Figure 35, the patent cites the angles that coincide with the touchscreen behaviors. Any manufacturer can deviate from the angles shown in Figure 35 to mitigate the patent’s specificities.
