Microsoft Corp filed a motion on Friday to remind the U.S Bureau of Customs and Border Protection of the enforcement of the ban on some imported Google Android devices which will prohibit such devices from entering the U.S market due to infringement issues.

Numerous cases of high tech patent lawsuits have been filed so far at the U.S International Trade Commission. In May 2012, the commission had concluded that the Motorola Mobility by Google has infringed a patent of Microsoft related to calendar generating and synchronizing features. Since then, any patent infringing device of Motorola Mobility had been barred by the commission from entering the U.S imported goods section.

The ban had naturally affected all those phones that have the Android software of Google. The company had retaliated by saying that it should only be applicable to some Android phones from the Motorola Mobility line-up.

The ban was expected to take effect after 60 days of its implementation. However, Microsoft has observed that the court ruling has not yet been enforced. They complained that the Customs and Bureau Protection has periodically allowed Motorola to be impassive of the order.

"CBP (Customs and Bureau Protection) has repeatedly allowed Motorola to evade that order based on secret presentations that CBP has refused to share with Microsoft," the complaint said.

Meanwhile, Google tried to interpret the situation by accusing Microsoft of attempting to go beyond the ruling of the ITC. This attempt by Microsoft has been rejected naturally by the Customs which explained that there was no substantial reason for the company to block people from using their phones’ legitimate and authentic calendar features such as setting up appointments and meetings.

"U.S. Customs appropriately rejected Microsoft's effort to broaden its patent claims to block Americans from using a wide range of legitimate calendar functions, like scheduling meetings, on their mobile phones," said Matt Kallman, a Google spokesman, in an interview with Reuters.

A spokesman from the U.S Customs refused to comment about this complaint.

The court filing involving Microsoft and Google is the latest patent-related issue flooding over the international patent arena which had caused relations between several smartphone manufacturing companies to turn sour. In reality, the discernment of a patent-infringing product is now made more difficult since the world is now transitioning into being more dependent on high technology.
