Tesla publishes thousands of words in official blog

June 12, Tesla in the official blog published "All our patent Are belong to You", announced the "opening of all Tesla technology patents," a voluminous thousands of words, set off a stir. When Apple, Samsung, Google for patent lawsuits, and penny-pinching, when most companies would like to hide their patents in the safe, Tesla in the opposite direction, announced "open" all patents.

So, why did Tesla open the patents, and why should they be opened?

Does Tesla have any "open" patents?

In fact, when we carefully read the "All our patent Are belong" to you the original text, you will find that maybe things are not just what we see, hear, in fact, there are some things behind the opening of Tesla.

Yesterday, there is a wall of Tesla patents in the lobby of our Palo Alto. That's no longer the case. Tightly have been removed, in the spirit of the "open source movement, for the advancement of Tepco vehicle.

We often see the first is this relatively small and fresh, small literary declaration. Translation into Chinese is:

Yesterday, Tesla's patents were also contained in the headquarters of Alto, which is no longer present. Inspired by the open source movement, Tesla will tear down the wall and promote the development of electric vehicles.

In fact, the following sentence is more critical, it is often overlooked.

Tesla won't initiate patent
Lawsuits against anyone who
Faith, wants to the use of our Marvell.

Translated to:

Tesla will not initiate patent lawsuits against any company that has a bona fide use of our technology.

There are actually two issues involved here:

1. Right of Action

2, the use of good faith

3. Other rights

The waiver was a formal waiver of the patent, and Tesla had only published its official blog, so the act had no legal effect. In the blog, Tesla made it clear that Tesla's abandonment was not a patent but a litigious right to use it in good faith. So Tesla or the patentee can recover the "open" right. These patents were Tesla's until the formal "waiver of patent" document was signed.

Tesla will not initiate patent lawsuits against any company that has a bona fide use of our technology. What is the use of goodwill? Tesla's official blog did not give a definition.

In addition, there is no mention of any rights other than these patents. For example, if a new patented technology has been developed on the basis of these publicly available technology patents, there may also be disputes over the attribution of these patents.

What patents did Tesla "open"?

Now, there are about 249 patents that Tesla can find on a U.S. patent website. For specific patents interested in children's shoes can be clicked link view. Most of these patents are related to the battery safety control system, including battery cooling system, safety system, charge balance system and so on.

Tesla's most important is the 8000 batteries in the car. According to gigaom2011, the batteries were not developed and manufactured by Tesla itself, but were purchased by Panasonic's ncr18650b batteries. As a result, this part of the patent still belongs to Panasonic, Tesla does not have a patent, this part of the patent is actually Tesla can not open.

In addition, even if this part of the patent is open, it is worth pondering over whether it will be adopted. ncr18650b use but electrolyte, slightly careless will cause the internal pressure of the battery to rise, explode. As of February this year, 5 incidents of Tesla bombings have taken place. At present, BMW, Toyota and other car manufacturers have chosen to develop lithium-iron batteries, battery density close to ncr18650b, security is also better. Domestic manufacturers, including BYD, have their own battery patents.

Why should Tesla "open" the patent?

In business, this is definitely out of Tesla's own development needs.

Tesla believes that their real rivals are not those not Tesla electric cars, but the daily production of petrol vehicles on the production line. The most important thing to do is to overcome the petrol car and increase the user's willingness to buy Tesla.

Tesla is currently charging mainly through home charging piles, super charging stations and destination charging stations. But the number of charging piles and filling stations is still very small. Take the super charging station for example, in North America only 86, in Asia only 3 (all in China), obviously can not meet the needs of car owners. "Open" patents are likely to speed up the construction of the charging infrastructure.

There are also standard problems with the fast charging station in addition to the facilities. The current mainstream 3-level rapid charge has three standards, respectively, Europe and the United States (Ford, General, Volkswagen, Audi, and Daimler, etc.) the main push of the Saecombo standard, Japan (Nissan, Mitsubishi, etc.) the main push of the CHAdeMO and Tesla main push of the super charging station. Standard dispute, the winner is often only one, Tesla to tens of thousands of of electric vehicles to contend with another two standards, the odds are not big.

Tesla was initially committed to setting standards, so it was incompatible with two other standards, and in the end, Tesla was unable to use a public charging station and other electric vehicles could not use a super charging station.

The charge standard problem does not solve, the charge pile does not fall, the electric vehicle defeat petrol car's prospect is not optimistic.
