Another feature of this disclosure is to provide the method of transmitting an information message by with a code polar, and a device to perform the process.

Additional features are described in part in the description which follows and, in a part, will be apparent from the description or may be learned by practice of the presented embodiments.

A method of transmitting signals by means of a Polar Code described in accordance with an aspect of the disclosure. The method involves generating a first codeword by applying the polar code to an input signal and then dividing the codeword in a plurality of partial vectors, and allocating at least one shaping bit to the input signal when at least one of partial vectors does not meet a predetermined Hamming weight condition, generating a second codeword using the polar code to theshaping bit allocated input signal, and transmitting the signal in accordance with the second codeword.

The division of the initial codeword could include, if the at-least one shaping bit includes 2.sup.r shaping bits, dividing the first codeword consisting of N bits into 2.sup.r partial vectors with the length of

##EQU00001## The Hamming weight condition is defined so that, based on the target probability of a first codeword, the Hamming Weight of every plurality of partial vectors is more than or is less than

##EQU00002## which corresponds to one-half of the length

What is a patent?

A patent is issued by the government to protect an invention. It grants the inventor the rights to create, use and sell the idea. Society benefits when new technologies are brought for sale. These benefits could be realized immediately by people who are able to achieve previously impossible feats, or indirectly through the opportunities for economic growth that innovation provides (business growth, jobs).

Patent protection is sought out by many pharmaceutical companies and university researchers for their work in research and development. Patents are granted to a product, process, or method for making new materials. Patent protection is granted to any invention that is beneficial unique, innovative, and not already known by others in the same field.

Patents are awarded to inventors who have commercially viable inventions. They act as an incentive for inventors to come up with new ideas. Small-scale businesses and inventors are assured that they will get an income from their investment in technology development via patents. They can earn a living from their work.

Businesses with the ability to:

Protect innovative products and services;

Improve the visibility and the value of your product’s presence on the market

Stand out and differentiate yourself and your product from the competition.

Find out about business and technical information.

Beware of accidentally using content from third parties or losing important data, creative outputs, or any other creative output.

Patents transform the knowledge of inventors into a marketable asset, that opens new avenues to create jobs by licensing joint ventures and joint ventures.

Small companies that have patent protection will be more appealing to investors who are involved in the commercialization of technology.

Patents can lead to the development of new ideas and new inventions. This information can encourage innovation and may qualify for protection under patents.

Patents are a way to stop untrustworthy third parties from profiting from the invention’s efforts.

Patent-protected technology revenues that are commercially profitable can be used for financing technological research and development (R&D) that will improve the chances of better technology in future.

Intellectual property ownership is a way to convince investors and lenders that there are real opportunities to commercialize your product. Sometimes, one powerful patent can lead to numerous financing possibilities. Patents as well as other IP assets can be used as collateral or security for debt financing. Investors may also look at your patent assets in order to increase their company valuation. Forbes and others have pointed out that each patent can increase between $500,000 and one million dollars to your company’s valuation.

Startups require a carefully-crafted business plan that leverages the IP to show that your product/service is unique and superior or ingenuous. Additionally, investors will be impressed if you can show that your IP rights are secure or in progress of being secure and that they support your business strategy.

It is important to keep an invention secret until you submit for patent protection. Public divulging an invention could often damage its novelty and render it invalid. Pre-filing disclosures, such as for investors, test-marketing, or other business partners, should be done only after signing a confidentiality contract.

There are many kinds of patents. Understanding the different types of patents is vital to protect your invention. Utility patents protect new techniques and machines. Design patents cover ornamental designs. Utility patents are best to protect the proprietor from copies and competitors. Most often they are granted for alterations or improvements to existing inventions. They can also be used to enhance or alter existing inventions. A process patent will describe the methods or actions to perform a specific action. However, a chemical composition will include an amalgamation of ingredients.

What is the typical length of a patent? While utility patents last up to 20 years from the initial filing, they are able to be extended through delay at the patent office.

Are you interested in similar patents? These are the steps:

1. Create a list of terms for your invention according to its function, composition, or use.

Write down a concise, but precise explanation of your invention. Be sure to avoid using terms that are generic such as “device,” “process,” and “system.” Instead, consider synonyms to the terms you initially chose. Next, note important technical terms and key words.

Use the following questions to help you identify the keywords or concepts.

  • What is the goal of the invention Is it a utilitarian device or an ornamental design?
  • Is the invention a method of creating something or performing a function? Or is it a thing or procedure?
  • What is the basis of the invention? What is the physical structure of the invention?
  • What’s the objective of this invention?
  • What are the terms in the technical field and the keywords used to describe an invention’s nature? To assist you in finding the correct terms, consult the technical dictionary.

2. These terms will let you search for pertinent Cooperative Patent Classifications on the Classification Search Tool. If you are unable to determine the correct classification for your invention, scan through the classification’s class Schemas (class schedules). If you don’t get any results using the Classification Text Search, you might consider substituting your words to describe your invention using synonyms.

3. Examine 3. Check the CPC Classification Definition to confirm the validity of the CPC classification you’ve found. If the selected classification title has a blue box with the letter “D” at its left, clicking on the link will lead you to the CPC classification’s description. CPC classification definitions can assist you in determining the classification’s scope of application so that you can choose the one that is most appropriate. They may also provide research tips or other suggestions that could be helpful for further research.

4. The Patents Full-Text Database and the Image Database allow you to find patent documents that are accompanied by the CPC classification. You can look through and find the relevant patent publications by looking first at abstract and the drawings that are representative.

5. Take advantage of this list of most relevant patent publications to study each in detail for similarity to your idea. Be sure to read the claims and specification. Contact the applicant as well as the patent examiner for additional patents.

6. Search for patent applications that have been published using the CPC classification you chose in Step 3 from the Applications Full-Text and Image Database. It is also possible to use the same search strategy that you employed in step 4 to limit your search results to only the most relevant patents by reading the abstracts as well as the drawings on each page. After that, you must review the patent applications that have been published carefully and pay particular attention to the claims and other drawings.

7. Locate other US patent publications using keywords in the PatFT or AppFT databases, classification search of non-U.S. patents according to below, and searching non-patent literature disclosures of inventions using web search engines. Examples:

  • Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
  • Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
  • Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.

To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
