A device that includes a substrate including a plurality of metal layers, and dielectric layers. The first passive component is also included in the device. It has a first terminal and a second terminal. The first terminal is connected to a ground signal that is first received while the second terminal is linked to another ground signal so that the first passive component is shorted.


Devices that include an underlying substrate and a passive surface that is mounted to it have various features.


Surface mount technology (SMT) is a technology that allows components to be installed or placed directly on a surface of a printed circuit board or package substrate. Surface mounting of passive components, like resistors and capacitors, can be done to package substrates that are used for radio frequency applications (RF) and voltage regulation and other purposes.

It is important to develop smaller devices that have efficient design structures that are cost-effective in order to solve problems such as electromagnetic interference, heat loss, and effective inductance tuning.

Devices that have an underlying substrate and a surface mount passive part that is mounted to it have various features.

The first example shows the substrate that is made up of a variety of metal layers and a plurality dielectric layers. A first passive component is also part of the device. It comprises a primary terminal as well as a second. Furthermore the body that is first fixed to the substrate using one of the metal layers. The first terminal is connected to a first ground signal while the second terminal is linked to a second ground signal such that the first passive component is cut off.

The second example demonstrates a method for fabricating a packaged passive component. It includes the provision of the substrate with a number of metal layers and a plurality dielectric layers. The method further involves attaching a first passive component to the substrate on one of the plurality of metal layers, the first passive comprising one terminal, a second, and a first body, and coupling the first terminal with the first ground signal as well as the second terminal to a ground signal in a manner that the first component is cut off.

What is a patent?

The government grants patents to protect an invention, patents give the inventor with the exclusive right to create, use to sell, and market the invention? society benefits when a new technology is introduced into the marketplace. The benefits can be realized immediately by people who are able to accomplish feats previously unattainable, or indirectly through the economic benefits that innovation offers (business growth, employment).

A lot of pharmaceutical firms and university researchers are seeking patent protection to protect their research and development. Patents are granted for the creation of a product, process or method of creating new materials. Patent protection has to be granted to any invention that is valuable, novel, and not already known by others in the same area.

Patents are awarded to inventors who have commercially viable inventions. They act as a motivator for inventors to create. Patents permit entrepreneurs and inventors to know that there’s an excellent chance that they will get a profit for their efforts, time and money spent on the development of technology. They can earn money from their work.

Companies that are able to:

Secure your products and services

Improve the visibility and the value of your products on market

Differentiate your business and products from the competition;

Find business and technical information.

Avoid the risk of using proprietary third-party content or losing important information, creative outputs, or another creative output.

Patents transform inventors’ information into a tradeable asset which opens new opportunities for job creation and business growth through joint ventures or licensing.

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

Patenting can lead to the development of innovative ideas and inventions. These information may be protected by patents.

Patents can be used to stop untrustworthy third-party companies from earning from the invention’s efforts.

Commercially successful patent-protected technology revenues can be used to fund the development of technology through research and development (R&D) that will improve the chances of developing better technology in the future.

Intellectual ownership of property can be used to convince lenders and investors that there are legitimate chances to market your product. A single patent could lead to many financing opportunities. Patents can be used along with other IP assets as collateral or security financing. You can also show investors your patent assets to increase the value of your business. Forbes and others have pointed out that every patent can boost the value of a company by anything from $500,000 to $1 million.

A well-designed business plan is essential for start-ups. It must be built on IP and explain what your service or product stands out. Investors will also be impressed if you prove that your IP rights are secured or are in progress of being secure and that they are in line with your business strategy.

It is essential to keep your invention private until you apply to protect it with patents. The public disclosure of an invention can be detrimental to its originality and render it invalid. Thus, disclosures that are filed prior to filing (e.g., for test-marketing investors, investors, or for other business partners) should only be filed upon signing a confidentiality contract.

There are several types of patents, and understanding the different types is crucial to protect your invention. Patents for utility cover methods and inventions made by machines. Design patents cover ornamental designs. Utility patents are best and shield the owner from copies and competitors. Frequently, utility patents are issued for alterations or improvements to existing inventions. Utility patents can also be used to improve or alter existing inventions. A process patent will describe the methods or actions of performing a particular act. But, a chemical composition would include an amalgamation of ingredients.

What is the typical length of a patent? While utility patents are valid up to 20 years from their earliest filing, they are able to be extended through delays at the patent office.

Are you planning to protect your idea? Patents are granted only for applicants who are first to file and you must start filing quickly. Call a patent attorney at PatentPC to protect your idea today!

Patent searches are a must when you are drafting an application for patent. This will enable you to see other concepts and provide insight into the potential of them. This will allow you to restrict the scope of your invention. It is also possible to discover the current state of the art within your field of invention. This will allow you to comprehend the scope of your invention and prepare you to file your patent application.

How to Search for Patents

The first step in obtaining your patent is to perform an internet search for patents. You can do a google patent search or do a USPTO search. After the patent application has been filed, the item covered by the application can be referred to as patent-pending and you will be able to locate the patent application online on the public pair. When the patent office has endorsed the patent application, you can perform a patent search to find the issued patent and your product is now patented. You can also utilize the USPTO search engine. Read on for more details. Patent lawyers or a patent attorney can assist you with 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. This office also reviews trademark applications.

Interested in finding more similar patents? These are the steps you should follow:

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

Write down a concise, precise description of your invention. Do not use generic terms such as “device”, “process”, and “system”. Instead, think about synonyms for the terms you selected initially. Next, note important technical terms and keywords.

Use the questions below to help you find keywords or concepts.

  • What’s the purpose of this invention? Is it a utilitarian device or an ornamental design?
  • Does the invention consist of a method of making something or performing a task? Is it a product or procedure?
  • What is the composition and function of the invention? What is the physical composition of the invention?
  • What is the goal of the invention?
  • What are the terms in the technical field and keywords used to describe the nature of an invention? To find the correct terms, consult an online dictionary of technical terms.

2. These terms allow you to find pertinent Cooperative Patent Classifications on the Classification Search Tool. To find the most appropriate classification to your invention, look through the classification’s class Schemes (class schedules). If you don’t see any results from the Classification Text Search, you might consider substituting your words that describe your invention using synonyms.

3. Check 3. Check the CPC Classification Definition for confirmation of the CPC classification you’ve found. The link to the CPC classification definition is provided if the chosen classification title has a blue box that includes “D” on the left. CPC classification definitions can help you determine the applicable classification’s scope so that you can choose the one that is most appropriate. Additionally they can provide search tips and other suggestions that may be useful for further study.

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 find the most relevant patent publications.

5. This list of patent publications is the most appropriate to examine for similarity to your idea. Be sure to read the specification and claims. Contact the applicant as well as the patent examiner to obtain additional patents.

6. Find patent applications published in the public domain using the CPC classification you selected in Step 3 of the Applications Full-Text and Image Database. It is possible to use the same search strategy in Step 4 to narrow your results to the most pertinent patent applications by examining the abstract and drawings that appear on each page. Then, you must carefully review the patent applications published, paying particular attention to the claims as well as additional drawings.

7. You can search for other US patent publications by keyword searches in AppFT or PatFT databases, as well as classification searching of patents that are not issued by the United States per below. You can also make use of search engines on the internet to find non-patent patent disclosures in literature 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:
  • 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.
