What is a patent?
A patent is issued by the government to safeguard an invention. The patent grants the inventor the exclusive rights to develop, use and sell the invention. Society benefits when new technology is introduced to the market. Benefits can be realized in direct terms, as it allows people to do previously impossible things. Or indirectly, by the economic benefits (business expansion and job creation) that innovation provides.
A lot of pharmaceutical firms and university researchers are seeking patent protection for their research and developments. Patents can be granted for the creation of a product, process or method for making new materials. In order to be granted protection under a patent, an invention has to be beneficial or novel, as well as not readily apparent to anyone else in the same area.
Patents give inventors a chance to be recognized for commercially viable inventions. They provide a reason for inventors to invent. Patents allow inventors and small businesses to be confident that there’s an excellent chance that they will receive a return on their time, effort and money spent on technological development. They can earn a living from their work.
Patents are a crucial part of businesses with the ability to:
Make sure you protect your unique products and services
Increase the value, visibility, and attractiveness of your products on the market;
Differentiate your business and products from others;
Get business and technical details.
Avoid the risk of accidentally using third-party proprietary content or losing important information, creative outputs, or another creative output.
Patents effectively transform the inventor’s knowledge into a marketable asset, which creates new opportunities for job creation and business expansion by licensing or joint ventures.
Small businesses that have patent protection are 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 patent protection.
Patents can be used to prevent untrustworthy third parties from making money from the invention’s efforts.
Commercially successful patent-protected technology revenues can be used to fund research and development (R&D), which will boost the likelihood of improved technology in the coming years.
Intellectual property ownership is a way to convince investors and lenders that there are real opportunities to market your product. One powerful patent may provide numerous financing options. Patents and other IP assets can be utilized as collateral or security for debt financing. Investors can also see the patents you own to increase the value of your company. Forbes and other publications have pointed out that each patent could increase the value of a company by anything from $500,000 to $1 million.
Startups require a carefully-crafted business plan that builds on the IP to show that your product or service is unique and superior or ingenuous. In addition, investors will be impressed if you can prove that your IP rights are secure or in the process of becoming secure and that they align with your business plan.
It is crucial to keep your invention secret until you file for patent protection. Public divulging an invention could often damage its novelty and invalidate it. Therefore, prior filing disclosures (e.g. for testing-marketing investors, test-marketing, or for other business partners) should only be made following the signing of a confidentiality agreement.
There are a variety of patents and knowing these is vital to safeguard your invention. Utility patents are for the development of new methods and machines. Design patents cover ornamental designs. Utility patents are the most effective and protect the owner against copycats and competitors. Most often the utility patent is issued to improve or modify existing inventions. Utility patents also cover improvements and changes in existing inventions. For instance, a process patent covers acts or methods of performing a specific act, whereas chemical compositions are an assortment of ingredients.
What is the length average of a patent? Patents for utility last 20 years from the earliest filing dates, but their expirations can be extended because of patent office delays 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 filed, the product covered by the application can be called patent-pending, and you can locate the patent application on public pair. After the patent office approves your application, you will be able to do an examination of the patent number to discover the patent granted. Your product will be patented. You can also utilize the USPTO search engine. See below for details. Patent lawyers or a patent attorney can advise you on 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 examines trademark applications.
Are you interested in finding similar patents? Here are the steps:
1. Create a list of terms that describe your invention based upon the purpose, composition and use.
Write down a brief and precise explanation of your invention. Do not use generic terms such as “device,” “process,” and “system.” Instead, look for synonyms to the terms you selected initially. Next, note important technical terms and key words.
Utilize 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 an action? Or is it a product or process?
- What is the nature and purpose of the invention? What is the physical structure of the invention?
- What is the goal of the invention?
- What are the terms and phrases in the field of technology that describe the nature of an invention? To help you find the correct terms, consult the technical dictionary.
2. Use these terms to search for relevant Cooperative Patent Classifications on the Classification Text Search Tool. To find the best classification to your invention, scan the resulting classification’s class Schemes (class schedules). If you don’t get any results using the Classification Text Search, you may want to consider replacing the words for describing your invention with synonyms.
3. Examine the CPC Classification Definition for the CPC Classification Definition to confirm the accuracy of the CPC classification that you have located. The link to the CPC classification definition is available if the chosen classification title is a blue square with a “D” to its left. CPC classification definitions can help identify the specific classification’s scope, so you are certain to choose the one that is appropriate. Additionally, these definitions can include some tips for searching and other information that may be useful for further research.
4. Retrieve patent documents with the CPC classification from the Patents Full-Text and Image Database. You can look through and narrow down the relevant patent publications by focusing first on the abstract and the drawings that are representative.
5. This collection of patent publication is the best to examine for similarity with your invention. Pay close attention to the claims and specifications. Refer to the applicant and patent examiner for additional patents.
6. You can find published patent applications that fit the CPC classification you selected in Step 3. You can apply the same method of search in Step 4 to narrow your search results to the most relevant patent application through the abstract as well as the illustrations on every page. Next, examine every patent application that has been published with care, paying special attention to the claims, and other drawings.
7. You can look up additional US patent publications using keyword search in AppFT and PatFT databases, and also classification searching of patents not from the United States according to below. Additionally, you can use web search engines to find non-patent patent disclosures in literature about inventions. 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:
- 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.
