The steps to make an one-dimensional nano-structure-based device include the following steps: Step (1), preparation of an solution (14) using one-dimensional micro-structures (15); step (2), providing two electrical conductors (10 and 12) each with their own tips (101 and 121); step (3) is to apply only a small amount of solution to the tips of these conductors, resulting in the tips becoming connected; step (4), applying voltage (16) between them, thereby at minimum one one-dimensional shape being connected to at minimum one of the electric conductors at the tips; and Step (5).

1. Field of the Invention

The present invention is related to nano-structure-based devices, and particularly to a method of manufacturing a single-dimensional device based on nano-structures.

2. Discussion of the Related Art

Many nano-scale structures can be created artificially using fields including silicon nano-threads and carbon nanotubes. Nano-structures are being integrated into a variety of fields, such as, field effect transistors, sensors, and AFMs. (AFMs).

For example, as regards the AFM, the probe tip of the AFM typically has the nano-structure of carbon nanotubes or a single carbon nanotube. The following methods are used to attach the carbon nanotube/tubes to the probe tips: (1) Drawing a bundle of carbon Nanotubes , or one carbon nanotube from bundles of Carbon Nanotubes using an optical microscope; (2) placing the carbon nanotube/tubes onto a probe tip using another AFM; (3) creating the carbon nanotube/tube extension with the probe tip.

However, the above-mentioned methods have common shortcomings, because they are complex procedures, take a lot of time, and have low production efficiency.

What’s needed, therefore, is to provide a method to manufacture a nano-structure-based device that is simple to control, and which is also more efficient in terms of time.

A method for making a nano-structure-based one-dimensional device that is described herein typically comprises the steps involved in preparing an emulsion containing one-dimensional nano-structures and supplying a pair of electrical conductors that each have a tip, the tips thereof being separated from and opposed to one another; applying the solution to the tips of the electrical conductors the tips thereby being interconnected with the solution, applying an electric voltage to the two conductors thereby atleast one one-dimensional nano-structure is connected to at least one tip of the electrical conductors; and then removing the liquid solvent of the solution.

These and other aspects, aspects, and advantages of the nano-structure-based one-dimensional device will be more obvious through the detailed description and claims, and the accompanying drawings.

What is a patent?

A patent is granted by the government to safeguard an invention, patents grant the inventor exclusive rights to develop, utilize to sell, and promote the invention?society gains when a innovative technology is introduced into the marketplace. These benefits may be directly realized when people are able to achieve previously unattainable feats or indirectly via the economic opportunities that innovation provides (business expansion, jobs).

Patent protection is demanded by many pharmaceutical companies and university researchers for their research and development. Patents can be granted for the creation of a product, process or method of creating new materials. In order to be granted protection under a patent an invention has to be novel, useful, and not obvious to anyone else within the same field.

Patents reward inventors who have commercially successful inventions. They provide a motivation for inventors to create. Patents allow entrepreneurs and inventors to know that there’s an excellent chance that they will receive a return on their time, effort and investment in technological development. They could earn a decent income by their work.

Patents play essential roles in firms and can be used to:

Secure the latest products and services;

Increase the visibility and value of your product’s presence on the market

Stand out and differentiate yourself and your product from others.

Get technical and business information.

Avoid accidentally using content from third parties or losing valuable information, original outputs, or any other outputs that are creative.

Patents transform inventor’s knowledge into a valuable asset that opens new avenues for employment creation by licensing joint ventures and joint ventures.

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

Patenting can generate fresh ideas and innovative inventions. This information can encourage the development of new ideas and may be eligible to be protected by patents.

Patents can be used to stop untrustworthy third parties from profiting through the work of inventions.

Commercially successful patent-protected technology revenues could be used to finance research and development (R&D), which will improve the chances of developing better technology in the coming years.

You can leverage the intellectual property rights of your company to convince lenders and investors that your product is a viable commercial value. Sometimes, one patent can open the door to multiple financing opportunities. Patents can be used along with other IP assets as collateral or security for financing. Investors may also look at the patents you own to increase their company valuation. Forbes and other publications have reported that each patent can increase anything from $500,000 to a million dollars in company valuation.

A well-constructed business plan is vital for new businesses. It must be built on IP and show the way your product or service is distinctive. Investors will also be impressed if you have IP rights are secured or are on the verge of being secured, and they agree with your business plan.

It is important to keep your invention secret until you submit to protect it with patents. Making an invention public prior to filing can frequently degrade its originality and make it patent-infringing. Therefore, pre-filing disclosures (e.g., for test-marketing, investors, or other business partners) should only be filed following the signing of a confidentiality agreement.

There are many types of patents. Understanding them is crucial for protecting your invention. Utility patents cover new processes and machine creations. Design patents cover ornamental designs. Utility patents are the best since they protect the owner from copycats and other competitors. Frequently, utility patents are issued for improvements or modifications to existing inventions. Utility patents also cover improvements and changes in existing inventions. A process patent could describe the methods or actions of performing a specific act. A chemical composition would include the combination of components.

What is the typical length of a patent? Patents that are utility-related last for 20 years from the earliest filing date, but their expiration dates may be extended because of delays at the patent office, for example.

Do you wish to patent your ideas? Patents are granted only to applicants who file first, you need to make your application quickly. Contact PatentPC to speak with a patent attorney PatentPC to file your invention today!

A patent search is essential when you’re preparing an application for patent. This allows you to view other ideas and give you insights into their work. You’ll be able to reduce the nature of your invention. Additionally, you’ll be able to learn about state of the art in your field of innovation. You’ll be able to get a better idea of what your invention ought to be, and you’ll be more prepared to submit the patent application.

How to Search for Patents

The first step to get your patent is to perform a patent search. You can do a google patent search or do a USPTO search. Patent-pending refers to the product protected by the patent application. You can use the public pair to locate the patent application. When the patent office is satisfied with your application, you will be able to do a patent number look to locate the patent that was issued. Your product now has the potential to be patentable. You can also use the USPTO search engine. See below for details. For assistance, consult an attorney who specializes in patents. 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.

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

1. Think of terms to describe your invention based upon its purpose, composition, and use.

Write down a brief detailed explanation of your invention. Don’t use generic terms such as “device”, “process,” or “system”. Think about synonyms for the terms you picked initially. Then, take note of important technical terms and key words.

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

  • What’s the goal of this invention? Is it a utilitarian device or an ornamental design?
  • Does the invention consist of a method of creating something or a function? Or is it a thing or procedure?
  • 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 nature of an invention? A technical dictionary will help you locate the right terms.

2. These terms will allow you to search for pertinent Cooperative Patent Classifications on the Classification Search Tool. To determine the most suitable classification to your invention, scan the resulting classification’s class Schemes (class schedules). Think about substituting the words that you’re using 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 the first step.

3. Examine 3. Go over the CPC Classification Definition to verify the validity of the CPC classification you’ve discovered. The hyperlink to the CPC classification definition will be available when the classification you have selected is a blue square with a “D” to its left. CPC classification definitions will help you determine the applicable classification’s scope , so you can select the one that is most appropriate. Furthermore, these definitions can include some tips for searching and other information which could be helpful 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 the abstracts and representative drawings you can narrow your search to find the relevant patent documents.

5. Use this selection of the most relevant patent publications to look at each in detail for similarities to your invention. Take note of the specification and claims. Contact the applicant as well as the patent examiner for any additional patents.

6. You can retrieve published patent applications that match the CPC classification you chose in Step 3. You may also employ the same strategy of searching you utilized in Step 4 to narrow down your results to the most relevant patents by reading the abstracts and drawings for every page. Next, carefully examine the published patent applications with particular attention paid to the claims and additional drawings.

7. You can search for additional US patent publications using keywords in the AppFT and PatFT databases, as well as classification searching of patents that aren’t from the United States as in the following table. You can also use web search engines to search for non-patent-related documents that describe inventions in the literature. 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.
