Why does Coca Cola Company fail to protect their receipe with patents?

We shall remember that, at any time, choices of IP protection shall always rest on profitability. If the patent protection make people lose money, then people would choose to avoid that.

By patenting the receipe of coke, Coca Cola company have to DISCLOSE the receipe to the world. In return, the receipe MAY be protected for a max of 20 years. After the protecting period expires, Coca Cola receipe falls into public knowledge, and anyone may use it anywhere.

Register patent in Vietnam

It is not so easy to crack the coke receipe. Why would Coca Cola disclose their receipe to exchange for a short protection?

Surely, if the receipe is disclosed accidentally, anyone in the world may begin to use this receipe, and numberous competitors appear. In order to minimize the harm brought by the possible competitors, Coca Cola has invested a lot of money on their Trademarks and Scale of Production.

Now Coca Cola have a famous brand. Even two coke products taste the same, you would still choose Coca Cola.

By holding huge scale of production, Coca Cola is able to produce coke at a very very low cost. Even when another company begin to produce the same coke, they can never make coke this cheap.

Even when it is profitable to patent your product, you may still see no “patent” directly linked to a particular “product model”. See iPhone. Thousand of patents may be linked to the product, and there is no patent to protect “iPhone X”. We may need such strategies to mislead competitors, max the protection range, …

How do I write a good provisional patent application?

A provisional patent - as you may already know - helps you buy some time (up to a year ) as you market and possibly develop your idea. This way, if the idea gains traction at some point during the year, you can convert this provisional patent to a fully-fledged utility patent. If not this, you can simply let it expire or lapse after testing the waters and realizing that it wasn't such a good idea to invest hundred of hours and thousands of dollars paying for a utility patent.

Nationalize PCT Patent Application in Vietnam

That being said, here is a quick primer on how to craft a provisional patent:

1. Research Thoroughly

Even before of thinking of filing for a provisional patent, you should first of all do a comprehensive patent search to know whether or not the idea you are interested in has already received another patent protection. Apart from that, conducting a separate search to ascertain that there haven't been any similar inventions that are patented is also a good way of avoiding a corporate lawsuit later. At the same time, you are also likely to come across suggestions of many available unpatented ideas that are in case yours is already taken. Either way, doing a thorough patent search is inevitable as long as you are considering to copyright your innovation.

2. Be Simple, Focused but Thorough

The provisional patent application ought to paint the picture of a unique innovation by listing the specific features/benefits that prove its novelty. In other words, a well-thought and thorough profile is likely to increase the chances of your application getting approved.

3. The Application Package

The full application package ought to tie in the following;

a. The specification of the innovation

b. A drawing of the innovation

c. The filing fee

d. The USPTO Cover

As far as the main body goes, it should consist of the Description of the Innovation, Tittle, Abstract, and the Claim.

Nowadays, you also have to include the drawings of the invention. These can be scanned into the main text area, sketched by hand or designed by CAD, manuals, design software or Powerpoint. Next up is the Claims that describe in detail what the patent seeks to protect. You don't have to include this, but it is recommended that you have them on your provisional patent application.

Lastly, you will have to paste an abstract that summarizes your invention. For this part, it is easier to re-state ( in a few words ) what you had described in the Claims.
