The case relates to the 'bounce back' feature in Motorola phones that allegedly infringes Apple's patented technology in its iOS operating system.
This follows an earlier case in which Samsung was hit with a $1bn+ damages bill after losing a patent and design fight to the iPhone maker.
Both Samsung and Motorola use Google's Android operating system.
Apple can now decide whether to pursue a sales ban against Android phones and tablets in Germany, although Google is expected to appeal.
A court in Munich (September 13) issued a verdict against Motorola, relating to the system that makes lists of data bounce back when the user reaches the end.
Judge Dr Peter Guntz said that Motorola infringed the patent for "overscroll bounce", or "rubber-banding" held by Apple.
Writing on the Foss Patents blog, he said that Motorola could easily get a workaround by moving to the "stock" version of Android that displays a blue glow when the user reaches the bottom of the list rather than the overscroll bounce. Samsung's newer devices already operate this system.
However, Mueller - who has previously done work for Google - added: "But the glow does not solve the problem that the rubber-banding patent solves: by the time a user notices the glow, he or she has already instinctively pressed harder because of the impression that the device is not responding. This injunction spells further degradation of the Android user experience."
He feels that Google will definitely appeal the decision of the Munich court and also continue to pursue its challenge against Apple's 'bounce back' patent.
After Apple won $1.05bn (£648m) in damages from Samsung, the firm's co-founder Steve Wozniak said that he "hated" the fact that Apple was engaged in such disputes.
"I don't think the decision of California will hold," he told Bloomberg at the time. "And I don't agree with it... I wish everybody would just agree to exchange all the patents and everybody can build the best forms they want to use everybody's technologies."
Meanwhile, there has been speculation that Samsung will join HTC in suing Apple over the Long Term Evolution technology used for its new iPad and the recently announced iPhone 5.
Apple is in turn seeking US sales bans on various Samsung phones and tablets, including the popular Galaxy S3 handset.
