What is a patent?
The government grants patents to protect an invention, patents grant the inventor with exclusive rights to create, use, sell and promote the invention? society benefits when a new technology is brought into the marketplace. These benefits could be directly realized as people are able to achieve previously unattainable feats or by the opportunities for economic growth which innovation can bring (business growth, employment).
Many pharmaceutical companies and university researchers seek patent protection to protect their research and development. Patents may cover an abstract or physical product or process or composition or method of making materials that are completely new to the area. To be granted patent protection the invention must be innovative, novel and not apparent to others in the same subject.
Patents are a way to reward inventors for their commercially successful inventions. They are an incentive to inventors to come up with new ideas. Small companies and inventors can be assured that they will get the most return from their investment in technology development through patents. They could earn a decent income by their work.
Businesses with the ability to:
Secure new products and services that are innovative;
Enhance the value, appearance, and visibility of your products market;
Differentiate yourself and your products from the competition.
Access to business and technical knowledge and information;
Beware of accidentally using content from third parties or loosing valuable information, innovative outputs or any other output that is creative.
Patents transform inventors’ knowledge into a commercially tradeable asset, which creates new opportunities for job creation and expansion of businesses through joint ventures or licensing.
Small businesses that have patent protection will be more attractive to investors involved in the commercialization of technology.
Patenting can lead to innovative ideas and inventions. This information can encourage innovation and may qualify for patent protection.
Patents can be used as an obstacle to unscrupulous third parties that profit from an invention’s efforts.
Commercially successful patent-protected technology revenues can be used to finance technological research and development (R&D), which will boost the likelihood of improved technology in the near future.
Intellectual property ownership is a way to convince lenders and investors that there are genuine opportunities to commercialize your product. Sometimes, a single patent could lead to multiple financing opportunities. Patents and other IP assets can be utilized as collateral or security to finance debt. Investors may also look at your patent assets in order to increase their company valuation. Forbes and others have stated that each patent can increase the value of your company by as much as $500,000 to $1 Million.
Start-ups require a well-designed business plan that is built on the IP to demonstrate your product or service is distinctive or superior to others. Investors are also impressed if you have IP rights are secured or are on the verge of becoming secure, and that they support your business plan.
It is vital to protect an invention before submitting a patent application. A public disclosure of an invention can frequently devalue its originality and render it invalid. The filing of disclosures prior to filing, for example, for investors, test-marketing, or other business partners, should only be done after the signing of a confidentiality agreement.
There are many kinds of patents, and understanding the different types is crucial to protect your invention. Utility patents are for new processes and machine creations. Design patents cover ornamental designs. Utility patents are the best because they shield the owner from copycats as well as other competition. Utility patents are often granted to enhance or modify existing inventions. Utility patents can also be used to cover improvements and modifications in existing inventions. For example, a process patent covers acts or methods of doing a specific act, whereas chemical compositions will comprise a mixture of components.
How long does a patent last? While utility patents last up to 20 years from their earliest filing, they can be extended by delay in the patent office.

How to Search for Patents
A patent search is the initial step in obtaining your patent. You can do a google patent search or do a USPTO search. Patent-pending refers to the product that has been protected by the patent application. It is possible to search the public pair to locate the patent application. When the patent office is satisfied with your application, you’ll be able to do search for a patent number and discover the patent granted. The product you are selling will then become patented. In addition to the USPTO search engine, you may also use other search engines like espacenet as described below. It is possible to seek help from a patent attorney or patent attorney. Patents in the United States are granted by the US trademark and patent office or the United States patent office. The trademark office also evaluates trademark applications.
Interested in finding more similar patents? Here are the steps to follow:
1. Think of terms that describe your invention according to its function and composition or usage.
Begin by writing down a concise detailed description of your idea. Avoid using generic terms like “device,” “process,” and “system.” Instead, consider synonyms to the terms you chose initially. Then, take note of important technical terms and key words.
To help you identify keywords and concepts, use the following questions.
- What is the objective of the invention? Is it a utilitarian device or an ornamental design?
- Invention is a method to create something or perform an action? Is it a product?
- What is the composition and function of the invention? What is the physical structure of the invention?
- What’s the point of this invention?
- What are the technical terms and terms that define the nature of an invention? A technical dictionary can help you identify the correct phrases.
2. Utilize these terms to locate relevant Cooperative Patent Classifications at the Classification Text Search Tool. If you are unable to find the right classification for your invention, go through the classification’s Schemas of classes (class schedules). Think about substituting the words that you’re using for describing your invention, if you don’t receive any results from the Classification Text Search with synonyms such as the terms you used in step 1.
3. Go through 3. Go over the CPC Classification Definition to verify the relevancy of the CPC classification that you have found. The link to a CPC classification definition is provided in the event that the title of the classification contains a blue box with “D” on its left. CPC classification definitions will help you determine the applicable classification’s scope , so you can choose the one that is most appropriate. Furthermore, these definitions can include research tips and other suggestions which could be helpful for further study.
4. Retrieve patent documents with the CPC classification from the Patents Full-Text and Image Database. You can review and select the relevant patent documents by looking first at abstract and the drawings that are representative.
5. This list of patent publications is the best to look at for any connections with your invention. Pay close attention to the claims and specifications. There are many patents available by referring to the patent examiner as well as the applicant.
6. Search for patent applications that have been published using the CPC classification you selected in Step 3 from the Applications Full-Text and Image Database. You may also employ the same search strategy that you used in step 4 to limit your search results to only the most relevant patent applications by looking over the abstracts and representative drawings for each page. The next step is to review every patent application that has been published with care, paying special attention to the claims, and other drawings.
7. Locate additional US patents by keyword searching in PatFT or AppFT databases, classification searches of non-U.S. patents per below, and searching for non-patent publications of inventions with internet search engines. 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:
- European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents.
- Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
- World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
- Korean Intellectual Property Rights Information Service (KIPRIS)
- State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
- Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
- 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.
