Longitude Licensing Limited v. Google, LLC

Background

Longitude Licensing Limited sued Google, LLC concerning claims in four patents: the ’365, ’574, ’056, and ’109 patents. The opinion states that the patents concern improving image quality by adjusting aspects of an image based on features of the image’s main object.

Google moved to dismiss. Longitude argued, among other things, that claim construction was needed because terms such as “image data,” “pixel values,” “pixel data,” and “image data of a photographed image” might have technical meanings beyond their apparent meanings. Longitude also discussed an alleged improved image-file structure in the ’109 patent and argued that the claims described a specific way to improve a prior computing process.

Court’s Analysis

The court held that the claims were directed to an abstract idea under 35 U.S.C. § 101: improving image quality by adjusting different aspects of an image based on features of its main object. The court described the variations among the claims—including identifying a main object by recognizing a human face, considering an image’s location or background, and correcting color balance with a formula—as additional abstract ideas for enhancing an image.

The court ruled that implementing the idea on a computer did not make it eligible for patent protection. It found that the claims lacked an additional inventive concept because they were functional and focused on the desired result, rather than describing a specific technological method for achieving that result. The court also found the claims insufficiently detailed compared with cases involving specific technological improvements.

The court declined to credit Longitude’s conclusory allegations that the claims improved a prior computing process. It said Longitude needed to explain the nature of the alleged technological improvement rather than simply repeat claim limitations and assert that the claims improved technology. The court likewise found that Longitude had not explained how the alleged image-file structure improved the relevant technology. It rejected Longitude’s other arguments, reasoning that the claims did not become eligible merely because they might not preempt the entire field and that the additional claims discussed by Longitude had the same problems as the representative claims addressed in Google’s motion.

Disposition

Judge Vince Chhabria granted Google’s motion to dismiss because the claims in the four patents were directed to ineligible subject matter. The court dismissed with prejudice, stating that Longitude did not request leave to amend and that the complaint’s allegations and the patent language made clear that amendment would not cure the identified problems.
