What is a patent?

Patents are granted by the government to protect an invention. It gives the inventor the rights to develop, use and market the idea. Society is benefited when new technologies are introduced for sale. The benefits may be the direct sense, since it may allow individuals to achieve previously impossible things, or indirectly, by the economic benefits (business expansion and employment) that innovation provides.

Many drug firms and university researchers are seeking patent protection for their work and research. Patents can be granted to a physical or abstract product or process, or even the method or composition of materials unique to the field. Patent protection has to be granted to an invention that is useful or novel and is not already known by others in the same area.

Patents reward inventors who have commercially successful inventions. They provide a motivation for inventors to create. Small-scale businesses and inventors can be sure that they will earn the most return from their investment in technology advancement through patents. They can make a living by their work.

Patents are a crucial part of firms and can be used to:

Create and protect innovative products and services;

Improve the value, the popularity, and appeal of your product on the market;

Differentiate yourself and your products from the rest.

Access technical and business knowledge and other information;

Avoid the risk of accidentally using proprietary third-party content, or losing valuable information, innovative outputs, or other creative output.

Patents convert knowledge of the inventor into an asset that can be sold, that opens new avenues for employment creation through joint ventures and licensing.

Investors who are involved in the commercialization and development of technology may find small companies with patent protection to be more attractive.

Patenting can lead to innovations and new ideas. This information can promote the development of new ideas and may be eligible for protection under patents.

Patents can serve as an effective deterrent for untrustworthy third parties profiting from the invention’s success.

Patent-protected technology revenue that is commercially profitable can be used to finance technological research and development (R&D) which increases the likelihood for better technology in the future.

It is possible to use the intellectual property rights of your company to convince lenders and investors that your product has real commercial potential. A single patent could open the door for many financing options. Patents and other IP assets can be utilized as collateral or security for financing debt. Investors can also see your patent assets to increase company valuation. Forbes and other publications have reported that each patent can add between $500,000 and one million dollars to your company’s valuation.

A carefully designed business plan is essential for startups. It should be built on IP and show what your service or product is distinct. Investors will be impressed when your IP rights are secured or are in the process of becoming secure and they endorse your business plan.

It is important to keep an invention hidden until you apply to protect it with patents. Public disclosure of an invention can frequently devalue its originality and render it invalid. Pre-filing disclosures, such as for investors, test-marketing or any other business partners must be done after signing a confidentiality agreement.

There are several types of patents. Understanding these is vital to safeguard your invention. Patents for utility cover methods and inventions made by machines. Design patents cover ornamental designs. Utility patents are best and protect the owner against copies and competitors. Utility patents are often issued to improve or modify existing inventions. They can also be used to enhance or modify existing inventions. A process patent could be a way to describe the actions or methods of performing a particular act. However, a chemical composition will include an amalgamation of components.

What is the average length of patents? Utility patents are valid for 20 years after the earliest filing dates, but their expiration dates may be extended due to patent office delays for instance.

It is also possible to use the USPTO search engine. See below for details. A patent lawyer or attorney can help you through the procedure. Patents granted in the United States are granted by the US trademark and patent office, or the United States patent office and trademark office. The office also evaluates trademark applications.

Interested in finding more similar patents? These are the steps to follow:

1. Think of terms that describe your invention, based on its purpose, composition, or use.

Write down a concise detailed description of the invention. Do not use generic terms such as “device”, “process,” or “system”. Instead, consider synonyms to the terms you selected initially. Also, keep track of crucial technical terms as well as keywords.

To help you recognize the key words and concepts, try the following questions.

  • What is the goal of the invention Is it a utilitarian device or an ornamental design?
  • Is the invention a way of creating something or performing a function? Is it a product or procedure?
  • What is the composition of the invention? What is the physical structure of the invention?
  • What’s the point of the invention
  • What are the terms in the technical field and keywords used to describe the nature of an invention? To find the correct terms, consult the technical dictionary.

2. Utilize these terms to locate pertinent Cooperative Patent Classifications for your invention at the Classification Text Search Tool. If you’re unable to determine the correct classification for your invention, look through the Schemas of classes (class schedules). If you do not get results using the Classification Text Search, you may want to consider replacing the words for describing your invention using synonyms.

3. Review 3. Go over the CPC Classification Definition for the CPC Classification Definition to confirm the relevancy of the CPC classification you’ve found. If the selected classification title includes a blue square with an “D” at its left, the hyperlink will take you to the CPC classification definition. CPC classification definitions will help you determine the applicable classification’s boundaries so that you can select the one that is most appropriate. These definitions may also include search tips or other suggestions that can be useful for further investigation.

4. Get patent documents using the CPC classification from the Patents Full-Text and Image Database. You can look through and find the relevant patent publications starting with abstract and the drawings that are representative.

5. This collection of patent publication is the best to examine for similarity to your idea. Be sure to read the specifications and claims. It is possible to find additional patents by consulting the patent examiner and applicant.

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 strategy of searching you employed in Step 4 to narrow your search results to the most relevant patent applications by reviewing the abstracts and drawings on each page. Next, examine the patent applications that have been published carefully and pay particular attention to the claims, and other drawings.

7. You can find other US patent publications using keyword searches in AppFT or PatFT databases, and also classification searching of patents that aren’t from the United States as per below. Additionally, you can make use of search engines on the internet to search non-patent literature disclosures about inventions. For example:

  • 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.
