Google will assure standards organisations that it will license Motorola Mobility patents on a fair and reasonable basis, according to Reuters sources.

The report said a letter signed by a senior Google lawyer will be sent to the relevant authorities imminently, after a deadline set by the European Commission for Google to submit remedies related to its proposed US$12.5 billion purchase of Motorola Mobility passed.

Standards organisations likely to receive the assurance from Google include the European Telecommunications Standards Institute (ETSI).

Motorola Mobility holds more than 17,000 patents, which Google is likely to use to protect supporters of its Android platform in legal and licensing disputes with the likes of Apple and Microsoft.

A Google spokeswoman told Reuters that Motorola’s approach to patent licensing won’t change once it becomes part of Google and will continue to offer fair, reasonable and non-discriminatory terms.

European regulators will rule on Google’s plan to acquire Motorola Mobility by 13 February, a European Commission spokesman told the publication.
