2. Description of the Related Art
Organic light-emitting devices emit self-emitting devices with large viewing angles and high contrast, as well as quick response times and excellent qualities in terms of brightness as well as driving voltage , and speed. They also produce high-quality images.
One example of organic light-emitting devices is one that has a first electrode positioned on a substrate. The second electrode is sequentially placed on top of the first electrode. Holes emitted from the first electrode can be able to move towards the emission layer through the hole transport region and electrons emitted from the second electrode may be transported to the emission layer through the electron transport region.Carriers, such as electrons and holes, mix within the emission layer to produce excitons. These excitons move (e.g., transition or relax) from an excited state to a neutral state, which generates light.
Aspects of embodiments of the present disclosure offer an organic light-emitting device.
Additional features of embodiments will be set forth in part in the description which follows and, in part, will be evident from the description, or may be learned by application of the described embodiments.

What is a patent?
A patent is granted by the government to protect an invention, patents grant the inventor with the exclusive right to create, use, market and promote the invention?society is benefited when a brand innovative technology is brought into the market. These benefits may be directly realized as individuals are able to accomplish previously unattainable feats, or indirectly via the opportunities for economic growth that innovation provides (business growth, employment).
Many drug companies and researchers at universities seek patent protection for their research and developments. Patents can be granted to an abstract or physical product or process or a method or composition of materials that are completely new to the area. To be granted patent protection the invention must be novel, useful, and not obvious to anyone else within the same field.
Patents are awarded to inventors who have commercially viable inventions. They act as an incentive for inventors to create. Patents enable entrepreneurs and inventors to know that there is a good chance they will get a profit for their efforts, time, and money invested in technology development. This means they will be able to make a living by their work.
Patents play a vital role in firms and can be used to:
Protect your innovative products and services.
Increase the visibility and value of your product’s presence on the market
Make your company and products stand out from others;
Find business and technical information.
Avoid the risk of accidentally using third-party proprietary content, or losing your valuable data, original outputs, or another creative output.
Patents convert knowledge of the inventor into a marketable asset, which creates new opportunities to create jobs through joint ventures and licensing.
Small companies that have patent protection are more attractive to investors involved in the commercialization and development of technology.
Patenting can generate fresh ideas and innovative inventions. This information could be eligible for patent protection.
Patents can be used as a deterrent to non-trustworthy third parties who profit from the invention’s success.
Revenues from patent-protected technology that are commercially successful can be used to fund the development of technology through research and development (R&D) that will increase the chance of better technology in the coming years.
Intellectual property ownership is a way to convince investors and lenders that there are genuine opportunities to market your product. A single patent could lead to many financing options. Patents as well as other IP assets are able to be utilized as collateral or security to finance debt. You can also show investors the patents you own to increase the value of your business.

Additionally, investors will be impressed if you can show that your IP rights are secure or in the process of becoming secure and that they support your business plan.
It is essential to protect an invention before applying for patent protection. The public disclosure of an invention can often damage its novelty and invalidate it. The filing of disclosures prior to filing, for example, for investors, test-marketing or other business partners, must be done after signing a confidentiality contract.
There are many types of patents. Understanding them is crucial for protecting your invention. Utility patents protect new techniques and machines. Design patents cover ornamental designs. Utility patents are the best because they shield the proprietor from copycats and other competitors. Patents for utility are usually issued to improve or modify existing inventions. They can also be used to improve or modify existing inventions. A process patent could cover the acts or methods of performing a particular act. But, a chemical composition would include a combination of ingredients.

Are you interested in finding other similar patents? These are the steps to follow:
1. Brainstorm terms to describe your invention according to its function and composition or usage.
Write down a concise and precise description of the invention. Don’t use generic terms like “device”, “process” and “system”. Think about synonyms for the terms you picked initially. Also, make note of key technical terms and keywords.
Use the questions below 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 a function? Are you referring to a product?
- What is the purpose and composition of the invention? What is the invention’s physical structure?
- What is the goal of this invention?
- What are technical terms and phrases that define the nature of an invention? To assist you in finding the appropriate terms, use the technical dictionary.
2. Use these terms to find relevant Cooperative Patent Classifications at the Classification Text Search Tool. If you’re not able to locate the appropriate classification to describe your invention through the classification’s class Schemas (class schedules) and then try again. Think about substituting the words you’re using for describing your invention, if you do not get any results from the Classification Text Search with synonyms similar to the words you used in step 1.
3. Go through 3. Check the CPC Classification Definition for confirmation of the CPC classification you found. The hyperlink to a CPC classification definition will be provided when the classification you have selected contains a blue box with “D” to the left. CPC classification definitions can aid you in determining the classification’s scope, so you can choose the one that is most appropriate. Additionally the definitions may 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. By focusing on abstracts and drawings that are representative, you can narrow down your search to find the most relevant patent publications.
5. Utilize this list of most pertinent patent documents to look at each one in depth for any the similarities to your invention. Pay close attention to the specifications and claims. Refer to the applicant and patent examiner for any additional patents.
6. Retrieve published patent applications with the CPC classification you selected in Step 3 in the Applications Full-Text and Image Database. It is possible to use the same method of search as in Step 4. You can narrow your search results down to the most relevant patent applications by looking at the abstract as well as the drawings on each page. After that, you must review all published patent applications carefully with particular attention paid to the claims and other drawings.
7. You can find additional US patent publications by keyword searching in the AppFT and PatFT databases, as well as search for patents classified as that are not issued by the United States in the following table. Additionally, you can utilize web search engines to find non-patent patent disclosures in literature about inventions. 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.
