Search Patent for Nanocrystal particles with emissive properties, method of making the same, and device that includes an emissive nanocrystal

A core that contains a first semiconductor nanocrystal containing a Group III/V compound and the shell that houses an additional semiconductor Nanocrystal surrounding the core. The latter is an emissive particle of nanocrystal. The non-emissive Group I element is contained in the particles that emit.

1. Field

An emissive nanocrystal as well as a method of making the same, as well as a device including the emissive nanocrystal particles are disclosed.

2. Description of the Related Art

The physical properties of nanocrystal particles like melting points or energy bands are able to be changed to alter their sizes. This is different with bulk materials. For instance, asemiconductor nanocrystal also known as a quantum dot is a semiconductor material having crystal structures that are several nanometers in size. Nanocrystals of semiconductors are so small that they possess huge areas per volume. They also exhibit quantum confinement effects , and possess different physical properties than bulk materials. In other words, semiconductor nanocrystals could have different properties by controlling their physical size. Nanocrystals that are semiconductor can absorb light from sources of excitation, be excited, or emit energy that is in accordance with their energy bandgaps.

A vapor deposition method for metal organic chemical deposition (MOCVD), molecular be epitaxy (MBE) or similar processes that involve a wet chemical method consisting of introducing organicsolvents and precursor materials to form crystals, and other techniques that can be employed to make semiconductor nanocrystals. When using the wet chemical method, organic materials such as dispersing agents may be coordinated on, e.g., attached to the surfaces of semiconductor nanocrystals, to regulate the growth of crystals during crystal growth, andthus uniformity of shapes and sizes of semiconductor nanocrystals could be easily controlled compared with the vapor deposition method.

Semiconductor nanocrystals with an internal shell structure could show slightly enhanced quantum efficiency, however, it is possible to create technologies that enhance the properties (such like quantum efficiency) of nanocrystals.

What is a patent?

A patent is granted by the government to safeguard an invention patents grant the inventor with exclusive rights to use, create to sell, and promote the invention? Society gains when a innovative technology is introduced to the market. The benefits can be realized immediately when people can perform feats previously thought impossible and indirectly by the opportunities for economic growth that innovation offers (business expansion, job creation).

Many drug firms and researchers from universities are seeking protection from patents in their work and discoveries. Patents are granted to a product, process, or method of making new materials. In order to be granted protection under a patent an invention has to be useful, new and not be obvious to anyone else in the same field.

Patents reward inventors who have commercially successful inventions. They act as a motivator for inventors to invent. Small businesses and inventors are certain that they will receive an income from their investment in technology advancement through patents. They can earn a living through their work.

Businesses that have the capacity to:

Protect your innovative products and services

Improve the value, the visibility, and attractiveness of your products market

Your business and your products should be distinguished from others;

Access business and technical expertise and information;

Beware of accidentally using content from third parties or losing valuable information, original outputs or any other creative output.

Patents convert knowledge of the inventor into a valuable asset which creates new opportunities for employment creation through licensing and joint ventures.

Small companies that have patent protection are more attractive to investors involved in the commercialization of technology.

Patenting can generate innovative ideas and inventions. These information may be protected under 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 technological research and development (R&D) that will increase the chance of better technology in the future.

You can leverage the intellectual property rights of your company to convince lenders and investors that your product is a viable commercial potential. Sometimes, a single patent could open the door to a variety of financing possibilities. You can use patents and other IP assets as collateral or security to secure financing. Investors may also look at the patents you own to increase their company valuation. Forbes and others have pointed out that every patent could boost the value of a company by anything between $500,000 and $1 million.

Start-ups require a well-constructed business plan that is built on the IP to demonstrate that your product/service is distinct, superior, or innovative. In addition, investors will be impressed if you show that your IP rights are secured or on the verge of becoming secure, and that they align with your business strategy.

It is crucial to keep an invention secret until you submit for patent protection. A public disclosure of an invention could often damage its novelty and render it invalid. Therefore, prior filing disclosures (e.g. for test-marketing investors, test-marketing, or any other business partners) must only be done following the signing of a confidentiality agreement.

There are numerous types of patents. Understanding them is crucial to protect your invention. Utility patents protect new techniques and machines. Design patents cover ornamental designs. Utility patents are best and shield the owner from copycats and other competitors. In most cases the utility patent is issued to improve or modify existing inventions. Utility patents can also be used to enhance or alter existing inventions. A process patent would cover the acts or methods to perform a specific action. However, a chemical composition would include the combination of components.

What is the average length of patents? Patents for utility last for 20 years after the earliest filing date, but their expirations may be extended because of delays at the patent office, for example.

Are you thinking of patenting your ideas? Patents are granted only to applicants who are the first to file, so you must file quickly. Call PatentPC today to file your patent application filed!

Patent searches are essential when you’re writing an application for patent. This allows you to discover other concepts and provide insight into them. You’ll be able narrow down the nature of your invention. Additionally, you’ll be able to be aware of the current state of technological advancements in your area of invention. You’ll have a better idea of what your idea should be and will be more prepared to submit the patent application.

How to Search for Patents

A patent search is the very first step in obtaining your patent. You can do a google patent search or do a USPTO search. After the patent application is filed, the product covered by the application can be referred to as patent-pending and you can locate the patent application online on the public pair. Once the patent office approves the patent application, you can perform a patent search to locate the issued patent which means that your product is now patented. In addition to the USPTO search engine, you can also utilize other search engines like espacenet, as detailed below. It is possible to seek help from a patent attorney or patent attorney. In the US, patents are granted by the US patent and trademark office or the United States patent and trademark office, which also examines trademark applications.

Interested in finding more similar patents? Here are the steps:

1. Brainstorm terms that describe your invention based on its purpose, composition, and application.

Write down a succinct, precise description of your invention. Don’t use generic terms like “device”, “process,” or “system”. Instead, think about synonyms for the terms you initially chose. Next, take note of crucial technical terms as well as keywords.

Utilize the following questions to help you determine key words or concepts.

  • What is the objective of the invention? Is it a utilitarian device or an ornamental design?
  • Is invention a way to create something or perform an action? Does it constitute an item?
  • What is the purpose and composition of the invention? What is the physical makeup of the invention?
  • What’s the purpose of the invention?
  • What are technical terms and phrases that define the essence of an invention? To find the appropriate terms, use the technical dictionary.

2. These terms will allow you to find pertinent Cooperative Patent Classifications using the Classification Search Tool. To determine the best classification to your invention, scan the classification’s class Schemes (class schedules). Think about substituting the words you use to describe your invention if you fail to find any results in your Classification Text Search with synonyms such as the terms you used in step 1.

3. Check the CPC Classification Definition for confirmation of the CPC classification you’ve found. The link to a CPC classification definition will be given in the event that the title of the classification has a blue box that includes “D” to the left. CPC classification definitions can be used to identify the specific classification’s scope and therefore you’re certain to choose the one that is appropriate. They may also provide some search tips or other recommendations that can be useful for further investigation.

4. The Patents Full-Text Database and the Image Database allow you to retrieve patent documents that include the CPC classification. You can review and select the relevant patent publications by initially focusing on abstract and representative drawings.

5. This selection of patent publication is the best to examine for similarities to your idea. Be sure to read the claims and specifications. There are many patents available by referring to the patent examiner and the applicant.

6. You can find patent applications published in the past that fit the CPC classification you chose in Step 3. You may also employ the same search strategy that you used in Step 4 to narrow down your search results to the most relevant patent applications by looking over the abstracts and representative drawings for each page. The next step is to review all published patent applications carefully, paying special attention to the claims, and other drawings.

7. You can search for additional US patent publications by keyword searching in AppFT or PatFT databases, and also classification searching of patents not from the United States in the following table. Also, you can make use of search engines on the internet to find non-patent-related literature disclosures about inventions. 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:
  • 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.
