What is a patent?

Granted by the government to protect an invention patents give the inventor exclusive rights to develop, utilize to sell, and market the invention?society gains when a new technology is introduced into the marketplace. The benefits may be direct terms, as it allows people to do previously impossible things, or indirectly, by the economic benefits (business growth and employment) that the innovation offers.

Patent protection is demanded out by many university researchers and drug companies for their work in research and development. Patents can be granted to a product, process, or method of making new materials. Patent protection has to be granted to an invention that is useful, novel, and not previously known to others in the same area.

Patents are awarded to inventors who have commercially successful inventions. They act as a motivator for inventors to invent. Patents enable inventors and small companies to know that there’s an excellent chance that they will receive a return for their efforts, time, and money invested in the development of technology. They could earn a decent income through their work.

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

Protect new products and services that are innovative;

Improve the value, the appearance, and visibility of your products on the market;

Differentiate your business and products from others;

Access technical and business knowledge and other information;

Beware of accidentally using content from third parties or loosing valuable information, original outputs, or any other outputs that are creative.

Patents effectively transform the inventor’s knowledge into a commercially tradeable asset that opens up new possibilities for employment creation and expansion of businesses through licensing or joint ventures.

Small companies that have patent protection are more attractive to investors involved in the commercialization and development of technology.

Patents can lead to the development of innovative ideas and inventions. This information can encourage creativity and could be eligible for patent protection.

Patents can be used to prevent untrustworthy third parties from making money through the work of inventions.

Commercially successful patent-protected technology revenues can be used to fund the development of technology through research and development (R&D), which will improve the chances of developing better technology in the coming years.

Intellectual property ownership can be used to convince investors and lenders that there are legitimate opportunities to commercialize your product. Sometimes, one powerful patent can open the door to multiple financing options. Patents as well as other IP assets are able to be used as collateral or as security to finance debt. Investors can also see the patents you own to boost the value of your company. Forbes and other publications have stated that each patent can increase company valuation by anywhere from $500,000 to $1 million.

A well-crafted business plan is essential for new businesses. It must be based on IP and explain how your product/service is distinctive. In addition, investors will be impressed if you prove that your IP rights are secure or are in the process of becoming secure, and that they support your business strategy.

It is essential to keep an invention secret until you submit to protect it with patents. Public disclosure of an invention can often damage its novelty and make it invalid. Thus, disclosures that are filed prior to filing (e.g., for test-marketing, investors, or other business partners) must only be done following the signing of a confidentiality agreement.

There are a variety of patents. Understanding them is crucial for protecting your invention. Utility patents are for the development of new methods and machines. Design patents cover ornamental designs. Utility patents are the best since they protect the proprietor from copycats and other competition. They are typically granted to improve or alter existing inventions. Utility patents can also be used to cover improvements and changes in existing inventions. A process patent would be a way to describe the actions or methods of performing a particular act. But, a chemical composition would include the combination of components.

What is the average length of patents? While utility patents are valid for 20 years from the date of the initial filing, they can be extended through delay at the Patent Office.

Do you wish to protect your idea? Patents are granted only for first-to-file applicants and you must make your application quickly. Contact PatentPC to speak with a patent attorney PatentPC to protect your idea now!

When you’re writing a patent application, you should do a patent search. the search will give you an understanding of other people’s ideas. This allows you to limit the potential of your idea. Also, you can find out about the current latest developments in your field of invention. You’ll have a better idea of what your invention should be, and you’ll be better prepared for writing your patent application.

How to Search for Patents

The first step to get your patent is to conduct the patent search. You can do a google patent search or do a USPTO search. Once the patent application has been filed, the item subject to the application may be called patent-pending, and you will be able to locate the patent application on a public pair. When the patent office approves the patent application, you are able to do a patent number search to find the patent that was issued which means that your product is now patented. It is also possible to use the USPTO search engine. See below for details. A patent lawyer or attorney can help you through the process. In the US patents are issued by the US trademark and patent office or the United States patent and trademark office, which is also responsible for examining trademark applications.

Are you looking for similar patents? These are the steps to follow:

1. Think of terms to describe your invention, based on its intended purpose, composition and usage.

Write down a concise and precise description of the invention. Do not use generic terms like “device”, “process,” or “system”. Instead, consider synonyms to the terms you selected initially. Also, keep track of crucial technical terms and key words.

Utilize the following questions to help you find the keywords or concepts.

  • What is the purpose of the invention? Is it a utilitarian device or an ornamental design?
  • Does the invention consist of a method of creating something or fulfilling a purpose? Is it a product or procedure?
  • What is the composition of the invention? What is the physical composition?
  • What is the goal of this invention?
  • What are the terms in the technical field and keywords used to describe the nature of an invention? A technical dictionary can assist you to locate the right phrases.

2. These terms allow you to search for relevant Cooperative Patent Classifications using the Classification Search Tool. To determine the most suitable classification for your invention, go through the class scheme of the classification (class schedules). If you don’t get any results from the Classification Text Search, you might want to think about substituting the words for describing your invention with synonyms.

3. Go through 3. Go over the CPC Classification Definition to determine the relevancy of the CPC classification you’ve discovered. If the chosen classification is a blue box that has the letter “D” to its left, clicking on the hyperlink will take you to a CPC classification’s description. CPC classification definitions will help determine the relevant classification’s scope which is why you can be sure to choose the most pertinent. These definitions may also include research tips or other suggestions which could prove useful in further research.

4. Retrieve patent documents with the CPC classification from the Patents Full-Text and Image Database. By focusing on abstracts and representative drawings it is possible to narrow your search for the relevant patent documents.

5. This selection of patent publications is the most effective to examine for similarities with your invention. Be aware of the specification and claims. Contact the applicant as well as the patent examiner for additional patents.

6. Find patent applications published in the public domain using the CPC classification you chose in Step 3 from the Applications Full-Text and Image Database. You can apply the same search strategy in Step 4 to narrow your search results to the most relevant patent application through the abstract as well as the drawings that appear on each page. After that, take a close look at the patent applications that have been published, paying particular attention to the claims and the additional drawings.

7. You can find additional US patent publications by keyword searching in AppFT or PatFT databases, as well as classification searching for non-U.S. Patents as described below. Also, you can make use of search engines on the internet to search non-patent literature disclosures about inventions. For instance:

  • 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.
