SAMSUNG ELECTRO-MECHANICS CO., LTD. (Suwon-si, KR)

The present innovative concept aims to create a multilayer ceramic electronic component with an excellent electrical conductivity as well as bending strength.

According to a particular aspect of the current inventive concept, a multilayer ceramic electronic component comprises a ceramic body having dielectric layers and an internal electrode an electrode layer connected to the internal electrode, and a conductive resin layer that is disposed over the electrode layer and with conductive metals that has lower melting temperatures than the metal that conducts electricity, a conductive carbon and a base resin. Based on 100 percent of the metallic that conducts electricity, the conductive carbon is contained in the conductive layer. It could range between 0.5 to 5 parts in weight.

Another element of the ingenuous concept is that a multilayer ceramic ceramic electronic component comprises the body of a ceramic that has dielectric properties and an outer electrode and an electrode layer that is connected to with the electrode inside and the conductive layer. This layer comprises the conductive metallic, which is which has a lower melting temperature than the metal that conducts electricity and carbon that is conductive as well as a base resin. The conductive resin layer is two distinct peaks when analyzing the Raman analysis.

In accordance with another aspect of the present inventive idea, a multilayer ceramic electronic component comprises a ceramic body having first internal electrodes and second internal electrodes that are alternately stacked and have dielectric layers placed between them, and two external electrodes placed on the external surface of the body, and respectively linked to the first and second electrodes within the internal circuit. Each of the second and first external electrodes contains a conductive resin layer, which is comprised of an conductive metallic. This is a metallic with less melting temperatures than the metal that conducts electricity. The conductive layer also contains a conductive carbon. The conductivity of the conductive resin layer is ranging from 0.4 to 5.0 Wt.%.

Another feature of the innovative idea is that a multilayer component could be constructed from the body of a ceramic with dielectric layers with an internal electrode as well as an electrode layer. An electrode layer connects to the electrode inside. A conductor layer, which includes tin, which is a conductor metal that has an upper melting point than tin, a base material and graphene, also known as carbon black, is placed over the electrode. Based on 100 parts of the conductive metallic within the conductive layer, the tin (Sn) is present in the conductive resin layer in a quantity of 10-50 parts per weight.

What is a patent?

A patent is granted by the government to protect an invention. The patent grants the inventor the exclusive rights to create, utilize and sell the invention. Society benefits when new technologies are brought to market. The benefits may be directly, in that it may allow people to accomplish previously unattainable things. Or indirectly, by the economic benefits (business expansion and job creation) which the invention provides.

Many drug firms and researchers from universities are seeking protection from patents in their research and development. Patents can be granted to an abstract or physical product or process or a technique or composition of materials that are new to the field. To be granted patent protection the invention has to be beneficial unique, innovative, and not readily apparent to anyone else in the same subject.

Patents give inventors a chance to be recognized for commercially viable inventions. They act as an incentive for inventors to invent. Patents permit inventors and small businesses to be assured that there’s the possibility that they’ll be paid back for their time, effort, and money invested in technological development. They can earn money by their work.

Businesses with the ability to:

Protect the latest products and services;

Increase the visibility and value of your products ‘ presence on the market

Make your brand stand out from the rest.

Access to business and technical knowledge and other information;

Avoid using content that is third party or losing valuable information, innovative outputs or any other creative output.

Patents convert knowledge of the inventor into an asset that can be sold, which creates new opportunities for job creation through joint ventures and licensing.

Small companies that have patent protection will be more appealing to investors who are involved in the commercialization and development of technology.

Patenting can lead to new inventions and ideas. These information may be eligible for patent protection.

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

Patent-protected technology revenue that is commercially viable can be used to finance technological research and development (R&D) that can increase the chance of better technology in future.

It is possible to use intellectual property ownership to convince investors and lenders that your product has commercial value. A single patent could lead to many financing opportunities. Patents can be used in conjunction with other IP assets as collateral or security financing. Investors may also look at your patent assets in order to increase their company valuation. Forbes and others have noted that each patent can add anywhere from $500,000 to 1 million dollars to your company’s valuation.

A well-designed business plan is vital for startups. It should be founded on IP and show what your service or product stands out. 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 align with your business plan.

It is crucial to keep an invention secret before applying for patent protection. Public divulging an invention could frequently devalue its originality and render it invalid. Therefore, prior filing disclosures (e.g., for test-marketing investors, test-marketing, or for other business partners) must only be done after signing a confidentiality agreement.

There are a variety of patents, and understanding the different types is crucial to protect your invention. Patents for utility are used to protect the development of new methods and machines. Design patents cover ornamental designs. Utility patents are best and protect the owner against copies and competitors. Utility patents are often issued to improve or modify existing inventions. Utility patents also cover improvements and changes to existing inventions. For instance, a process patent will be able to cover actions or methods of performing a specific act, whereas a chemical composition will include the combination of components.

What’s the duration of a patent last? Patents for utility last for 20 years after the earliest filing dates, but their expirations may be extended because of patent office delays, for example.

Do you want to patent your ideas? Patents are only granted to the first applicants to file therefore you need to file your patent application quickly. Call PatentPC today to file your patent application filed!

When you are writing a patent application, you should do a patent search. the search will give you an understanding of other people’s concepts. This can help you limit the extent of your idea. You can also learn about the latest developments in the field you’re inventing. You’ll be able to get a better idea of what your idea should be and will be better prepared for writing your patent application.

How to Search for Patents

The first step to get your patent is to conduct an internet search for patents. You can do a google patent search or do a USPTO search. Patent-pending is the term for the product protected by the patent application. You can search for the public pair to locate the patent application. Once the patent office has approved your application, you’ll be able do a patent number look to locate the patent issued. Your product is now patent-able. Alongside the USPTO search engine, you can also utilize other search engines such as espacenet, as detailed below. 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, also known as the United States patent office and trademark office. This office also reviews trademark applications.

Are you interested in similar patents? Here are the steps to follow:

1. Create a list of terms that describe your invention based on its purpose, composition, and application.

Write down a short and precise explanation of your invention. Be sure to avoid using terms that are generic such as “device,” “process,” and “system.” Instead, consider synonyms to the terms you chose initially. Then, note important technical terms, as well as key words.

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

• What is the purpose of the invention Is it a utilitarian device or an ornamental design?
• Is invention a way to make something or carry out a function? Or is it a product or process?
• What is the composition and function of the invention? What is the physical structure of the invention?
• What’s the objective of this invention?
• What are the terms in the technical field and keywords that define the nature of an invention? To find the appropriate terms, use the technical dictionary.

2. Use these terms to find pertinent Cooperative Patent Classifications for your invention at the Classification Text Search Tool. To find the best classification to your invention, scan the class scheme of the classification (class schedules). Consider substituting the words that you’ve used for describing your invention, if you don’t find any results in your Classification Text Search with synonyms similar to the words you used in Step 1.

3. Check 3. Check the CPC Classification Definition to confirm the validity of the CPC classification you’ve found. The hyperlink to a CPC classification definition will be given when the classification you have selected has a blue box that includes “D” on its left. CPC classification definitions can aid you in determining the classification’s scope so that you can select the most relevant. Furthermore the definitions may include some tips for searching and other information that may be useful to further study.

4. Retrieve patent documents with the CPC classification from the Patents Full-Text and Image Database. You can review and narrow down the most relevant patent publications focusing first on abstract and representational drawings.

5. This list of patent publications is the most appropriate to check for connections to your idea. Pay attention to the claims and specifications. Consult the applicant and patent examiner for any additional patents.

6. Find patent applications published in the public domain using the CPC classification you picked in Step 3 in the Applications Full-Text and Image Database. You can apply the same search strategy as in Step 4. You can narrow your results down to the relevant patent applications by examining the abstract and drawings on each page. After that, take a close look at the patent applications published with particular attention paid to the claims and additional drawings.

7. You can search for other US patent publications using keyword searching in the AppFT and PatFT databases, and also the classification search of patents that are that aren’t from the United States as per below. You can also use web search engines to search non-patent literature disclosures about inventions. Here are some 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.
