Google has yet to respond to the reasons for this move, but we may be able to find the answer in patent records. Records show that the patents auctioned by Google originally belonged to Motorola Mobility, which Google acquired for $12.5 billion in 2011 (later sold to Lenovo).

　　At the time, Google was embroiled in legal disputes with mobile phone industry competitors such as Microsoft. The industry generally believes that the reason why Google is willing to spend money to acquire Motorola Mobility is because it takes a fancy to the latter's 17,000 patents, because it can use them to deal with a large number of legal proceedings.

　　However, this strategy is not a panacea. For example, last year, an appeals court found that Google had used some patents in bad faith and undermined its agreement on fair and reasonable licensing fees for "standard critical patents." Therefore, the court upheld its previous ruling that Google must pay Microsoft $14 million in compensation. .

　　Therefore, Google's patent auction is likely to get rid of some unnecessary assets rather than a major strategic transformation. Google is not only making a big push into the battery field, but is also working with automakers to develop self-driving cars.

　　Meanwhile, Google is pursuing a more low-key strategy to defend itself against intellectual property wars. It is reported that Google and other companies have established a patent alliance called "LicenseonTransfer" (LOT), promising to grant the use rights of these patents to other members of the alliance when selling patents externally. In addition, start-up companies that join the alliance can also obtain some patent licenses from the alliance.

　　Google has gradually become a patent "powerhouse" in recent years. According to a report on Wednesday, Google ranked fifth on the list of companies with the most patents last year.
