Google valued Motorola Mobility patents at $5.5 billion when it agreed to purchase the headset company earlier this year.
Newly-released company documents show how Google decided on its $12.5 billion dollar purchase price of Motorola Mobility. The documents show that the search giant valued Motorola Mobility's patents at a shade under half of the overall sale price of the company.
Google has said they hope to use the newly acquired patents to protect the Android ecosystem.
"On May 22, 2012, we completed our acquisition of Motorola, a provider of innovative technologies, products and services that enable a range of mobile and wire line digital communication, information and entertainment experiences," Google wrote in its Security and Exchange Commission filing on the purchase.
"The acquisition is expected to protect and advance our Android ecosystem and enhance competition in mobile computing."
Google and Motorola have faced a barrage of patent litigation over the past year. In Germany the newly merged companies scored a victory when a judge dismissed Apples claims that sales of the Motorola Xoom should be banned because of patent infringement.
In the US, Google patent drama has been an eye-opening affair. Judge Richard Posner had asked Apple and Motorola to settle the patent bickering and come to a settlement. Posner would later claim the patent case as proof that the US patent system was "out of sync".
By purchasing the Motorola Mobility patents Google may have an opportunity to curb future patent litigation. As referenced in the court documents, Google warns that patent litigation may hurt their bottom line moving forward.
"Regardless of the merits of the claims, intellectual property claims are often time consuming, expensive to litigate or settle, and cause significant diversion of management attention," Google went on to say the documents.
"To the extent such intellectual property infringement claims are successful; they may have an adverse effect on our business, consolidated financial position, results of operations, or cash flows."
Google's chief executive Larry Page made it clear to investors that the ownership of new patents was an important part of the Motorola Mobility purchase last year. Page specifically spoke to Apple litigation at the time of the announcement.
Samsung, who uses Google's Android OS, has also come under patent litigation fire. Apple is suing the headset maker for over $2.5 billion in damages.
