What is a patent?

A patent is granted by the government in order to protect an invention. The patent grants the inventor the sole right to create, use and sell the idea. Society is benefited when new technologies are brought for sale. These benefits could be realized immediately when people can achieve previously impossible feats, or indirectly through the economic benefits that innovation provides (business growth, employment).

Many pharmaceutical companies and researchers at universities seek patent protection for their work and research. Patents can be granted for a product, process, or method for making new materials. Patent protection has to be granted to any invention that is valuable unique, innovative, and not previously known to others in the same area.

Patents reward inventors for their commercially successful inventions. They serve as a motivator for inventors to invent. Small companies and inventors can be assured that they will get the most return from the investment they make in technology advancement through patents. This means they will be able to earn money from their work.

Patents play essential roles in companies, and they can:

Secure your products and services

Your products are more noticeable appealing, valuable, and desirable to customers.

Differentiate yourself and your products from others.

Find out about business and technical information.

Beware of using content that is third party or loosing valuable information, original outputs or any other outputs that are creative.

Patents transform inventor’s knowledge into an asset that can be sold, which opens up new opportunities for job creation through licensing and joint ventures.

Small companies that have patent protection will be more appealing to investors in the commercialization and development of technology.

Patenting can generate innovative ideas and inventions. This information can promote the development of new ideas and may be eligible for protection under patents.

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

Patent-protected technology revenue that is commercially profitable can be used to fund technology-related research and development (R&D) that can increase the chance for better technology in the future.

You can leverage the intellectual property rights of your company to convince investors and lenders that your product is a viable commercial value. Sometimes, a single patent can lead to multiple financing opportunities. You can use patents and other IP assets as collateral or security financing. Investors can also see your patent assets to increase the value of your company. Forbes and others have noted that every patent could boost the value of a company by anything from $500,000 to $1 million.

A well-crafted business plan is vital for start-ups. It should be based on IP and show how your product/service stands out. Investors will also be impressed when you prove that your IP rights are secure or in the process of becoming secure, and that they are in line with your business plan.

It is crucial to keep an invention secret until you file for patent protection. A public disclosure of an invention can be detrimental to its novelty and render it invalid. The filing of disclosures prior to filing, for example, for investors, test-marketing, or other business partners, must be done after signing a confidentiality agreement.

There are many kinds of patents. Knowing the different types of patents is vital to protect your invention. Utility patents cover new techniques and machines. Design patents cover ornamental designs. Utility patents are the most effective and shield the proprietor from copies and competitors. Most often the utility patent is issued for improvements or modifications to existing inventions. Utility patents also cover enhancements and modifications in existing inventions. For instance, a process patent covers acts or methods for performing an action, while chemical compositions will comprise an assortment of ingredients.

How long does a patent last? Utility patents last 20 years from the initial filing dates, but their expirations may be extended due to delays at the patent office such as.

How to Search for Patents

Patent searches are the first step towards obtaining your patent. You can do a google patent search or do a USPTO search. Once the patent application is submitted, the product that is that is covered by the patent application could be referred to as patent-pending and you can locate the patent application online on the public pair. Once the patent office has approved your application, you’ll be able to conduct an examination of the patent number to locate the patent that was issued. Your product now has the potential to be patentable. In addition to the USPTO search engine, you can use other search engines such as espacenet, which is described below. You can get help from a patent lawyer. Patents granted in the United States are granted by the US trademark and patent office as well as the United States patent office. This office also evaluates trademark applications.

Are you interested in finding similar patents? Here are the steps to follow:

1. Brainstorm terms that describe your invention based upon the purpose, composition and usage.

Write down a short and precise explanation of your invention. Avoid using generic terms such as “device”, “process,” or “system”. Consider synonyms for the terms you initially chose. Also, make note of key technical terms and keywords.

To help you recognize terms and keywords, you can use the questions below.

  • What is the objective of the invention? Is it a utilitarian device or an ornamental design?
  • Is inventing a method to create something or perform an action? Or is it a thing or procedure?
  • What is the structure of the invention? What is the physical makeup of the invention?
  • What’s the objective of the invention?
  • What are technical terms and phrases that define the characteristics of an invention? To assist you in finding the right terms, refer to an online dictionary of technical terms.

2. These terms allow you to look up pertinent Cooperative Patent Classifications using the Classification Search Tool. To find the most appropriate classification for your invention, scan the classification’s class Schemes (class schedules). Think about substituting the words you’re using for describing your invention, if you fail to receive any results from the Classification Text Search with synonyms like the ones you used in Step 1.

3. Go through 3. Go over the CPC Classification Definition to determine the accuracy of the CPC classification that you have found. If the chosen classification has a blue box that contains “D” and “D”, then the link to the CPC classification definition will be given. CPC classification definitions can be used to determine the relevant classification’s scope and therefore you’re certain to choose the one that is relevant. The definitions could also contain search tips or other suggestions that can be useful for further research.

4. Find patent documents that have the CPC classification from the Patents Full-Text and Image Database. You can look through and find the relevant patent publications paying attention to the abstract and drawings representative of.

5. This list of patent publications is the most appropriate to look at for any similarity with your invention. Be sure to read the specification and claims. Consult the applicant and patent examiner for any additional patents.

6. You can find patent applications published in the past that fit the CPC classification you selected in Step 3. It is also possible to use the same method of search that you employed in Step 4 to narrow your search results to only the most relevant patent applications by looking over the abstracts and representative drawings for each page. After that, you must review every patent application that has been published with care with particular attention paid to the claims, and other drawings.

7. Find additional US patent publications by keyword searching in PatFT or AppFT databases, classification searching of non-U.S. patents in the below, and searching non-patent literature disclosures of inventions using web search engines. Here are a few 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.
