This disclosure is related to wireless energy transfer sometimes called wireless power transmission.
Description of the Related Art
There are many methods to wirelessly transfer energy or power using radiative (or far-field) and non-radiative (or near-field) techniques. For instance the radiative wireless transfer of information using low-directionality antennas, such as thoseused in radio and cellular communication systems, as well as in computers at home, could be considered wireless energy transfer. This type of radiative transfer, however, is inefficient as only a small portion of the supplied power or radiated energy is absorbed. It’s just the portion that lies in the direction of the receiver and has a connection with it. The majority of power is scattered in all the different directions and is lost in the space. Such inefficient power transfer may be acceptable for datatransmission however it is not suitable to transfer useful quantities of electrical energy for the purpose of doing work for example, like charging or powering electrical devices. To enhance the effectiveness of radiative energy transfer techniques, directional antennas may be employed to direct radiation toward a receiver. However these directed radiation strategies could require an uninterrupted line of sight and potentially complicated tracking and steering systems for mobile transmitters or receivers. Additionally, these schemes may pose hazards for people or objects who are in the vicinity of the beam when modest to high quantities of power are transferred. An unidentified non-radiative or near-field wireless energy transfer technique commonly referred to either induction or traditional induction, doesn’t (intentionally) emit energy, but instead uses an oscillating current that passes through a primary coil, to create an oscillating magneticnear-field which causes currents to flow through the near-by receiving or secondary coil. Induction techniques have proven the transfer of moderate to large amounts of power, but only over extremely short distances and with very small offsettolerances between the primary power supply unit and the second receiver unit. Electric transformers as well as proximity chargers are two examples of devices using this short-range energy transfer technique, also known as near-field energy transfer.
Wireless power transfer system that is able to transfer useful quantities of electricity across long distances and offsets is required. This type of wireless power transfer would allow for energy transfer over greater distances and offsets compared to traditional induction methods. However, it’s not subject to the risks and disadvantages of radiative transmission techniques.Click here to view the patent on USPTO website.

What is a patent?
A patent is granted by the government to safeguard an invention, patents grant the inventor with exclusive rights to develop, utilize to sell, and promote the invention? society gains when a new technology is introduced into the marketplace. These benefits could be realized immediately by people who are able to accomplish feats previously unattainable as well as indirectly through the economic opportunities that innovation offers (business expansion, job creation).
Many drug companies and researchers at universities seek patent protection to protect their research and development. A patent can cover a physical or abstract product or process, or a method or composition of materials new to the field. In order to be granted protection under a patent an invention has to be innovative, novel, and not obvious to others within the same subject.
Patents are awarded to inventors who have commercially successful inventions. They act as an incentive for inventors to invent. Patents allow inventors and small businesses to know that there is the possibility that they’ll get a profit for their time, effort, and money invested in the development of technology. They can earn money from their work.
Businesses with the ability to:
Secure your products and services
Increase the visibility and value of your products ‘ presence on the market
Make your brand stand out from others.
Access to business and technical knowledge and data;
Beware of the possibility of using third-party proprietary content or losing important information, creative outputs, or any other innovative output.
Patents transform the knowledge of inventors into a valuable asset that opens new avenues for employment creation by licensing joint ventures and joint ventures.
Small businesses that have patent protection are more attractive to investors in the development and commercialization of technology.
Patenting may lead to new ideas and new inventions. This information could encourage innovation and may qualify for protection under patents.
Patents can be used to prevent untrustworthy third parties from profiting through the work of inventions.
Revenues from patent-protected technology that are commercially successful can be used to finance technological research and development (R&D) that will increase the chance of better technology in the near future.
It is possible to use intellectual property ownership to convince lenders and investors that your product has real commercial potential. A single patent could open the door for many financing opportunities. Patents as well as other IP assets are able to be used as collateral or security to finance debt. You can also show investors your patent assets to increase company valuation. Forbes and others have pointed out that each patent can add anything from $500,000 to million dollars to your company’s valuation.
A well-constructed business plan is essential for start-ups. It must be founded on IP and show how your product/service stands out. Investors will also be impressed if you can prove that your IP rights are secure or in the process of becoming secure and they are in line with your business plan.
It is crucial to keep the invention secret before applying for patent protection. A public divulging an invention could be detrimental to its originality and make it invalid. The filing of disclosures prior to filing, for example, for investors, test-marketing, or other business partners, is best done after signing a confidentiality agreement.
There are a variety of patents. Knowing them is essential to protect your invention. Utility patents protect new processes and machine creations. Design patents cover ornamental designs. Utility patents are the best since they protect the creator from copycats and competition. Frequently they are granted for modifications or improvements to existing inventions. Utility patents can also be used to enhance or alter existing inventions. For instance, a process patent will cover acts or methods of doing an action, while chemical compositions are the combination of components.
What is the typical length of the patent? Although utility patents last for 20 years from the date of their initial filing, they can be extended by delay in the Patent Office.
Are you interested in patenting your ideas? Since patents are only granted to first-time applicants and you must make your application quickly. Contact an attorney for patents at PatentPC to file your invention today!
A patent search is an essential step when you’re drafting the patent application. This will allow you to see other ideas and give you insight into their potential. This will allow you to restrict the potential of your idea. It is also possible to discover the current state of the art within your field of invention. You’ll get a better understanding of what your invention should be, and you’ll be better prepared to write the patent application.
How to Search for Patents
The first step to get your patent is to perform the patent search. You can do a google patent search or do a USPTO search. Patent-pending is the name used to describe the product protected by the patent application. You can search the public pair to find the patent application. After the patent office has approved the patent application, you are able to conduct a patent number search to locate the issued patent, and your product has now been granted a patent. You can also use the USPTO search engine. See below for details. You can get help from a patent lawyer. In the US patents are issued by the US patent and trademark office or by the United States patent and trademark office, which also examines trademark applications.
Interested in finding more similar patents? These are the steps:
1. Think of terms that describe your invention according to its function, composition, or use.
Start by writing down a concise and precise description of your idea. Be sure to avoid using terms that are generic such as “device,” “process,” and “system.” Instead, think about synonyms for the terms you initially chose. Also, make note of key technical terms and keywords.
Use the questions below to help you identify the keywords or concepts.
- What is the objective of this invention? Is it a utilitarian device or an ornamental design?
- Is the invention a method of making something or carrying out a function? Does it constitute an item?
- What is the structure of the invention? What is the invention’s physical composition?
- What is the purpose of the invention?
- What are the terms and phrases in the field of technology used to describe the nature of an invention? To find the appropriate terms, use an online dictionary of technical terms.
2. Use these terms to find relevant Cooperative Patent Classifications on the Classification Text Search Tool. To determine the most suitable classification for your invention, look through the classification’s class Schemes (class schedules). If you do not get results using the Classification Text Search, you might consider substituting your words that describe your invention with synonyms.
3. Go through 3. Go over the CPC Classification Definition to determine the relevancy of the CPC classification that you have discovered. The link to a CPC classification definition will be provided if the chosen classification title has a blue box that includes “D” on the left. CPC classification definitions will aid you in determining the classification’s scope so that you can pick the one that is the most appropriate. Furthermore they can provide research tips and other suggestions which could be helpful for further study.
4. Retrieve patent documents with the CPC classification from the Patents Full-Text and Image Database. You can review and select the relevant patent publications focusing first on the abstract and the drawings that are representative.
5. This selection of patent publications is the most appropriate to examine for connections to your idea. Pay attention to the claims and specifications. Refer to the applicant and patent examiner for additional patents.
6. You can find published patent applications that meet the CPC classification you chose in Step 3. You may also employ the same search strategy that you utilized in step 4 to limit down your results to just the most relevant patents by reading the abstracts and drawings for every page. After that, take a close look at the patent applications that have been published, paying particular attention to the claims and additional drawings.
7. Find additional US patents using keywords searching in PatFT or AppFT databases, classification searches of non-U.S. patents according to below, and searching non-patent patent disclosures in the literature of inventions using web search engines. Here are a few 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.
