2. Description of Related Art
The thermoelectric effect is the reversible and direct energy conversion between electricity and heat. It is caused by the transfer of electrons and holes within the material.
The thermoelectric effect may be classified into a Peltier effect as well as an Seebeck effect, in which the Peltier effect allows cooling by using a temperature difference between the ends of a thermoelectric material . It is generated through an applied current andthe Seebeck effect produces power by an electromotive force that is generated by a temperature difference between ends of the thermoelectric material.
Thermoelectric materials are used to cool electronic gadgets as well as semiconductor equipment. Passive cooling systems might not provide the appropriate thermal management. The demand for thermoelectriccooling is expanding into other cooling applications, such as precision temperature control for DNA synthesis, and the like, where providing suitable thermal control is difficult using a coolant gas compression system.
Thermoelectric cooling employs an extremely low-noise, non-vibration and eco-friendly cooling technique that does not use any gases used in cooling that could be harmful to the environment. Therefore, if a high efficiency thermoelectric cooling material is created that provides enhanced cooling efficiency, the application of thermoelectrics can be extended into general purpose cooling , such as air conditioning, refrigeration and similar.
Furthermore, if a thermoelectric material is positioned in an area where heat is released for example, a heat-generating part in an automobile engine or industrial plant, electricity can be produced. The technology is highlighted as a renewable energy source that is new.
Thermoelectric energy generation is utilized in space probes that are operating Mars and Saturn, where solar energy isn’t available.

What is a patent?
A patent is granted by the government to protect an invention, patents give the inventor with the exclusive right to use, create to sell, and promote the invention?society benefits when a new technology is brought into the marketplace. Benefits can be realized in the direct sense, since it can allow individuals to achieve previously impossible things. Or indirectly due to the opportunities for economic growth (business growth and employment) which the invention provides.
Patent protection is demanded by many universities and pharmaceutical companies for their research and development. Patents are granted for a product, process, or method for making new materials. To be granted patent protection an invention has to be useful, new and not apparent to others in the same subject.
Patents are a way to give inventors a reward for commercially profitable inventions. They serve as a motivator for inventors to invent. Patents permit entrepreneurs and inventors to know that there is an excellent chance that they will be paid back for their time, effort and investment in technology development. This means they will be able to earn a living from their work.

It is possible to use the intellectual property rights of your company to convince lenders and investors that your product is a viable commercial value. One patent that is powerful could open the door for numerous financing options. Patents and other IP assets can be used as collateral or as security for financing debt. Investors can also see your patent assets to increase the value of your company. Forbes and other publications have noted that every patent can boost company valuation by anywhere between $500,000 and $1 million.
A well-constructed business plan is crucial for new businesses. It must be founded on IP and show how your product/service stands out. Investors will be impressed when your IP rights are secured or are on the verge of being secured, and that they support your business strategy.
It is essential to keep your invention confidential until you apply for patent protection. The public divulging an invention could be detrimental to its originality and render it invalid. Disclosures that are filed prior to filing, like for investors, test-marketing, or other business partners, should be done only after signing a confidentiality agreement.
There are many types of patents. Understanding them is crucial to safeguard your invention. Utility patents are for inventions and processes that are new. Design patents cover ornamental designs. Utility patents are the best as they protect the owner from copycats as well as other competition. Utility patents are often issued to enhance or alter 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 an action, while chemical compositions are a mixture of components.
What’s the duration of a patent last? While utility patents are valid for 20 years from the date of their earliest filing, they can be extended by delay at the patent office.

Once the patent office approves the patent application, you are able to perform a patent search to locate the issued patent which means that your product will now be patented. Alongside the USPTO search engine, you can use other search engines such as espacenet, which is described below. A patent lawyer or patent attorney can assist you with the procedure. In the US, patents are granted by the US patent and trademark office, or the United States patent and trademark office, which is also responsible for examining trademark applications.
Are you interested in similar patents? These are the steps to follow:
1. Think of terms that describe your invention in relation to its intended and composition or use.
Begin by writing down a brief and precise description of your invention. Do not use generic terms such as “device”, “process” and “system”. Think about synonyms for the terms you picked initially. Then, note crucial technical terms and key words.
To help you find the key words and concepts, try the questions below.
- What is the objective of the invention Is it a utilitarian device or an ornamental design?
- Is inventing a method to make something or carry out an action? Does it constitute an item?
- What is the composition and function of the invention? What is the physical makeup of the invention?
- What is the goal of this invention?
- What are the terms in the technical field and keywords that define the nature of an invention? To help you find the right terms, refer to the technical dictionary.
2. Utilize these terms to locate relevant Cooperative Patent Classifications on the Classification Text Search Tool. If you’re not able to find the correct classification to describe your invention through the classification’s Schemas of classes (class schedules) and try again. If you don’t see any results using the Classification Text Search, you may consider substituting the words to describe your invention using synonyms.
3. Check the CPC Classification Definition for confirmation of the CPC classification you found. The hyperlink to the CPC classification definition is given when the classification you have selected has a blue box that includes “D” to its left. CPC classification definitions will help determine the relevant classification’s scope and therefore you’re certain to choose the one that is pertinent. Furthermore, these definitions can include some tips for searching and other information that may be useful for further research.
4. Find patent documents that have the CPC classification from the Patents Full-Text and Image Database. By focusing on abstracts and representative drawings you can narrow your search to find the most relevant patent publications.
5. Take advantage of this list of most relevant patent publications to look at each in detail for similarities to your own invention. Take note of the specification and claims. There are many patents available by consulting the patent examiner and applicant.
6. You can retrieve published patent applications that meet the CPC classification that you picked in Step 3. You can use the same method of search as in Step 4. You can narrow your search results down to the most pertinent patent application by examining the abstract and representative drawings on each page. Next, carefully examine the published patent applications and pay particular attention to the claims as well as additional drawings.
7. You can look up additional US patent publications by keyword searching in AppFT or PatFT databases, and also the classification search of patents that are not from the US according to below. Also, you can use web search engines to find non-patent patent disclosures in literature 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:
- 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.
