The number of patents a company files can show both how innovative and protected it is.

Some people in the tech industry have shied away from building up war chests full of patents. In a bold move last year, Elon Musk announced that Tesla would give away all of its patents for free. 

Tech companies are being pulled in two different directions they stock up on patents or give them up in the name of "co-opetition."

Using IFI Claims, we took a look at the tech companies that filed the most U.S. patents in 2014. 

No. 21 Toyota: 1,502 patents. Just recently, Toyota gave away 5,600 of its hydrogen fuel cell patents, similar to what Tesla did. Included in the patents given away for free were patents for the 2016 Toyota Mirai, the company's first fuel cell vehicle.

No. 20 Samsung Display: 1,511 patents. And going strong, as people are saying that the upcoming Samsung Galaxy 6 will have a three-sided touch display interface.

No. 19 Foxconn: 1,537 patents. The Taiwanese electronic-maker known for making Apple's iPhones and Sony's PlayStations is making a push into high-end manufacturing it recently patented a solar-power data center container that would benefit any company that runs large data centers.
