A method for manufacturing coils includes creating a plating resist over an internal insulating layer; making a coil pattern; and a lead pattern connected to the coil pattern, and at least partly having a thickness smaller than the coil pattern by plating, then removing the resist that was plating; and then putting one of the magnetic sheets on the internal insulating layer to form the body.

1. Field

The present disclosure relates to the coil component as well as manufacturing method for it.

2. Description of related art

Inductors, which are a kind of coil component, is a representative passive component of an electronic circuit together with a resistor and a capacitor to remove the sound.

It is possible to make a thin film inductor by plating, hardening and forming a magnetic powder-resin mixture, which is made of particles of magnetic powder and resin. Then, you form an outer electrode on the magnetic body.

In accordance with recent trends toward increased complexation, multifunctionalization, slimness of a set, and further decreased thickness of the thin film type inductor as described above, research has been continuously conducted.

An aspect of the present disclosure may provide a coil component and an approach to manufacturing it that can increase the binding force between a body and a coil part by forming a lead pattern to at least partially have a thickness less than the coil pattern.

According to a particular aspect of the disclosed invention, a manufacturing process of a coil component could consist of: forming a plating resist on an insulating layer inside; creating a coil pattern, and a lead pattern that is connected to the coil pattern, and at least partly having a thinner thickness than the thickness of the coil pattern by plating, then removing the plating resist and stacking an insulating sheet with a magnetic layer on the internal layer of insulation to form a body.

The plating resist may have an opening pattern that corresponds to the coil pattern, as and a hollow pattern that corresponds to the lead pattern. It should be in a relationship with this opening pattern and include an upper area that is partially covered by an enclosure.

In another way of the disclosed disclosure, coil components are made through the process of manufacturing.

What is a patent?

The government grants patents to protect an invention patents grant the inventor with exclusive rights to use, create and sell the invention? society gains when a new technology is introduced to the market. The benefits can be in the direct sense, since it may allow individuals to achieve previously unattainable things. Or indirectly through the economic opportunities (business growth and employment) which the invention provides.

Patent protection is sought by a variety of universities and pharmaceutical companies for their research and development. A patent can cover an abstract or physical product or process or a method or composition of materials unique to the area. Patent protection is granted to an invention that is beneficial, novel, and not already known by others in the same field.

Patents recognize and give inventors a reward for commercially successful inventions. They serve as a motivator for inventors to invent. Small-scale businesses and inventors can rest sure that they will earn an income from their investment in technology advancement through patents. They can earn a living from their work.

Companies that are able to:

Secure your products and services

Your product will be more visible appealing, valuable, and desirable to customers.

Your business and your products should be distinguished from others.

Get technical and business information.

Beware of accidentally downloading third-party content or losing valuable information, innovative outputs or any other outputs that are creative.

Patents transform the knowledge of inventors into a marketable asset, which opens up new opportunities to create jobs by licensing joint ventures and joint ventures.

Small-scale businesses with patent protection will be more appealing to investors who are involved in the commercialization and development of technology.

Patenting may lead to new ideas and new inventions. This information can promote creativity and could be eligible to be protected by patents.

Patents can serve as a deterrent to untrustworthy third parties who profit from an invention’s efforts.

Patent-protected technology revenue that is commercially profitable could be used for financing technology-related research and development (R&D) which can increase the chance for better technology in the future.

Intellectual ownership of property can be used to convince investors and lenders that there are genuine chances to commercialize your product. One patent that is powerful could lead to many financing options. Patents and other IP assets are able to be used as collateral or security to finance debt. You can also show investors your patent assets to boost company valuation. Forbes and others have stated 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 is built on the IP to show that your product or service is distinctive and superior or ingenuous. Investors will also be amazed if you have IP rights are secure or are on the verge of becoming secure, and that they agree with your business plan.

It is crucial to keep patent protection applications secret if you have an invention. Public divulging an invention could frequently devalue its originality and invalidate it. Pre-filing disclosures, such as for investors, test marketing, or other business partners should be done only after signing a confidentiality agreement.

There are a variety of patents and knowing them is essential to protecting your invention. Utility patents cover new processes and machine creations. Design patents cover ornamental designs. Patents that are utility-based are ideal to protect the proprietor from copycats and other competitors. Frequently they are granted for modifications or improvements on existing inventions. Utility patents also cover enhancements and modifications to existing inventions. A process patent could be a way to describe the actions or methods to perform a specific action. A chemical composition could be a combination of components.

What is the length average of patents? Although utility patents last up to 20 years from their initial filing, they can be extended by delays in the Patent Office.

Are you interested in the patenting of your idea? As patents are only granted to applicants who file first, you need to file quickly – call PatentPC to speak with a patent attorney PatentPC to patent your idea today!

When you’re writing an application for patents it is recommended to conduct an internet search for patents, since it will provide you with an insight into the other applicants’ concepts. This allows you to restrict the extent of your invention. You can also learn about the technological advancements in the field you’re inventing. This will allow you to know the extent of your invention and prepare you for filing the patent application.

How to Search for Patents

The first step to get the patent you want is to do the patent search. You can do a google patent search or do a USPTO search. After the patent application has been filed, the item that is covered by the patent application could be called patent-pending, and you will be able to locate the patent application on a public pair. When the patent office has endorsed the patent application, you are able to perform a patent search to find the patent that was issued and your product has been granted patent. In addition to the USPTO search engine, you can use other search engines such as espacenet as described below. A patent lawyer or patent attorney can assist you with the process. In the US patents are issued 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. Brainstorm terms that describe your invention, based on its intended purpose, composition and usage.

Write down a brief, but precise explanation of your invention. Do not use generic terms such as “device,” “process,” and “system.” Consider synonyms for the terms you initially chose. Then, take note of important technical terms as well as keywords.

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

  • What is the goal of the invention? Is it a utilitarian device or an ornamental design?
  • Is inventing a method to create something or perform an action? Are you referring to a product?
  • What is the basis of the invention? What is the physical composition of the invention?
  • What is the goal of the invention?
  • What are technical words and terms that describe the nature of an invention? A technical dictionary can assist you to identify the correct terms.

2. Use these terms to find pertinent Cooperative Patent Classifications for your invention at the Classification Text Search Tool. To find the most appropriate classification to your invention, go through the classification’s class Schemes (class schedules). If you don’t see any results from the Classification Text Search, you may want to consider replacing the words to describe your invention with synonyms.

3. Examine the CPC Classification Definition to verify the validity of the CPC classification that you’ve found. If the classification you have selected includes a blue square with an “D” to its left, the link will lead you to the CPC classification definition. CPC classification definitions can be used to identify the specific classification’s scope and therefore you’re sure to select the most appropriate. The definitions could also contain search tips or other suggestions that could be helpful for further research.

4. The Patents Full-Text Database and the Image Database allow you to retrieve patent documents that include the CPC classification. By focusing on abstracts and illustrations it is possible to narrow your search to the relevant patent documents.

5. This selection of patent publication is the best to look at for any similarities to your idea. Be sure to read the claims and specifications. It is possible to find additional patents by referring to the patent examiner as well as the applicant.

6. Retrieve published patent applications with the CPC classification you chose in Step 3 in the Applications Full-Text and Image Database. It is possible to use the same method of search as Step 4, narrowing your results to the most pertinent patent applications by examining the abstract and representative illustrations on every page. The next step is to review every patent application that has been published with care and pay particular attention to the claims as well as other drawings.

7. Locate additional US patents by keywords in the PatFT or AppFT databases, searching for classification of non-U.S. patents as described below, and searching non-patent patent disclosures in the literature of inventions using web search engines. 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:
  • 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.
