Two frames are utilized to create an assembly of filters. The two frames are linked by a hinge about which they turn. Between the two frames is an adsorbent media. One or more latches are used to lock the two frames. They are fixed to the rails on either side on at least one frame. The latches are flush with the edge on the side rails of the two frames, thereby joining two frames in a closed position.

The air in the indoors contains small particles that, if inhaled can cause serious health issues to people, including allergies, respiratory problems and so on. And when they’re just in the air, can damage devices, particularly those that have higher-sensitivity electronic components.In order to eliminate these particles, different kinds of air purifying devices, also known as air filtering devices are used. One of them is an electrostatic air filter device that uses electrostatic attraction to remove particles of fine size, such as dust and cigarette smoke from the air, such as is found in U.S. Pat. Nos. Nos. The electrostatic air filter device is able to charge particles that pass through the filter. This could increase the size of particles and make it easier to collect them within the filter. To attract the charged particles, the electrostatic filter is made up of a collection surface that could itself be charged, or might be a passive. After having passed through the filter, the air passing through it will be contaminated less pollutants.

The filtering media used in an electrostatic air filter device may be constructed from dielectric material for the filter. Frames could contain the filter media. They are attached to the frames with latches that can pivotally connect to them. The latches are secured to the frames’ outer edges. The latches extend beyond the frames’ edges and expand the overall dimension when it is closed. Due to this, the latches can catch during the installation and uninstallation of the filter assembly damaging not just frames which are simpler to repair or replace as well as the frames housings, which aren’t. This can impact the efficiency of the filter as air may bypassdamaged or misshapen filter elements, or it may even create an electrical connection that is damaged and reduce or even break them, rendering what was intended to be an electrostatic filter, merely a passive one.

Thus, there exists an urgent need for a more efficient latching mechanism that locks the frame of the electrostatic filter assembly.

It is the goal of this disclosure to provide a reliable sturdy, reliable, and simple way to handle electrostatic air filter making use of a more effective latching mechanism that locks the frames without extending beyond edges of the frames of the electrostatic air filter assembly.

According to an aspect of the disclosed disclosure, there is provided a filter assembly that may consist of a first frame and another frame. The first frame and the second are joined by a hinge about which they move and hold a filtermedia between them. The filter assembly includes at least one latch on a side rail of at least one of the first frame as well as the second frame. In order to join the frames first and second in closed positions the latches must be flush with the edges of the siderails of the frames that are the first and the second.

In accordance with another aspect of the disclosed disclosure, there is an assembly of filters that can comprise a first frame and another frame. The first frame as well as the second frame are joined by a hinge about which they rotate and hold an a filter media. The filter assembly contains at the very least one latch placed on the side rail of at minimum one of the frames, first and second. The at least one latch is flush with the edge of the side rails on the first frame and thesecond frame to connect the first frame and the second frame in a closed position. The latch is located at one or more edges of the side rail.

The present disclosure offers a way to minimize the incidence of problems that arise in the installation and removal of an electrostatic air filter. This will improve the efficiency and reliability of the assembly.

What is a patent?

A patent is granted by the government to protect an invention, a patent provides the inventor exclusive rights to create, use, market and promote the invention? Society is benefited when a brand new technology is brought into the marketplace. The benefits can be directly realized by people who are able to achieve previously impossible feats, or indirectly through the economic opportunities that innovation provides (business expansion, job creation).

Many drug companies and university researchers seek protection under patents to protect their research and development. Patents can be granted to products, processes, or method of creating new materials. To be granted patent protection the invention must be valuable or novel, as well as not readily apparent to anyone else in the same subject.

Patents honor inventors who have commercially successful inventions. They provide a reason for inventors to come up with new ideas. Patents allow entrepreneurs and inventors to be confident that there’s the possibility that they’ll receive a return on their time, effort and money spent on technological development. They can earn a living from their work.

Businesses with the ability to:

Protect your innovative products and services

Increase the visibility and value of your products on market

Your business and your products should be distinguished from the competition;

Get technical and business information.

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

Patents can transform an inventor’s knowledge into a marketable asset that opens up new possibilities to create jobs and boost business expansion by licensing or joint ventures.

Small businesses that have patent protection will be more attractive to investors in the development and commercialization of technology.

Patenting could lead to the development of innovative ideas and inventions. This information could encourage innovation and may qualify to be protected by patents.

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

Revenues from patent-protected technology that are commercially successful could be used to finance the development of technology through research and development (R&D) and boost the likelihood of improved technology in the near future.

Intellectual property ownership can be used to convince lenders and investors that there are real opportunities to commercialize your product. A powerful patent can provide numerous financing options. Patents as well as other IP assets can be utilized as collateral or security to finance debt. Investors may also look at the patents you own to boost their valuation of your company. Forbes and others have noted that every patent can boost company valuation by anywhere from $500,000 to $1 Million.

A properly-constructed business plan is essential for startups. It should be based on IP and explain what your service or product stands out. In addition, investors will be impressed if you demonstrate that your IP rights are secure or are in the process of becoming secure and that they support your business plan.

It is crucial to keep the invention secret before applying for patent protection. Making an invention public prior to filing can often destroy its novelty and make it ineligible for patent protection. 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. Understanding the different types is crucial to protect your invention. Utility patents protect new techniques and machines. Design patents cover ornamental designs. Patents for utility are the most effective since they protect the proprietor from copycats and other competition. Frequently they are granted for alterations or improvements to existing inventions. Utility patents can also be used to cover improvements and changes to existing inventions. A process patent could be a way to describe the actions or methods of performing a specific act. However, a chemical composition would include an amalgamation of ingredients.

What is the average length of a patent? Although utility patents last for 20 years from the date of their initial filing, they are able to be extended through delay in the Patent Office.

How to Search for Patents

Patent searches are the initial step to getting your patent. You can do a google patent search or do a USPTO search. Once the patent application is filed, the product that is covered by the patent application could be called patent-pending, and you can locate the patent application online on the public pair. When the patent office is satisfied with your application, you’ll be able to conduct an examination of the patent number to discover the patent granted. The product you are selling will then be patentable. In addition to the USPTO search engine, you can also utilize other search engines, such as espacenet as described below. For assistance, consult an attorney who specializes in patents. In the US patents are issued by the US trademark and patent office, also known as the United States patent and trademark office, which also reviews trademark applications.

Are you interested in similar patents? These are the steps to follow:

1. Create a list of terms that describe your invention based upon the purpose, composition and usage.

Start by writing down a concise, precise description of your invention. Be sure to avoid using terms that are generic such as “device,” “process,” and “system.” Instead, look for synonyms to the terms you selected initially. Next, note important technical terms and keywords.

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

  • What is the objective of the invention? Is it a utilitarian device or an ornamental design?
  • Is the invention a way of creating something or performing some function? Or is it a product or process?
  • What is the structure of the invention? What is the physical structure?
  • What’s the objective of this invention?
  • What are the technical terms and phrases that define the essence of an invention? To help you find the appropriate terms, use an online dictionary of technical terms.

2. Utilize these terms to find relevant Cooperative Patent Classifications on the Classification Text Search Tool. If you’re unable to locate the appropriate classification for your invention, scan through the class Schemas (class schedules) and try again. If you do not get results using the Classification Text Search, you might consider substituting your words to describe your invention using synonyms.

3. Check the CPC Classification Definition for confirmation of the CPC classification you have found. If the selected classification title is a blue box that has a “D” at its left, the link will lead you to a CPC classification description. CPC classification definitions can help determine the relevant classification’s scope which is why you can be sure to select the most pertinent. They may also provide some search tips or other recommendations which could prove useful in further study.

4. Find patent documents that have the CPC classification from the Patents Full-Text and Image Database. You can review and select the relevant patent publications by focusing first on the abstract and representative drawings.

5. Use this selection of the most relevant patent publications to study each in detail for similarity to your idea. Pay close attention to the specification and claims. Consult the applicant and patent examiner for any additional patents.

6. You can retrieve patent applications published in the public domain that fit the CPC classification that you picked in Step 3. You may also employ the same strategy of searching you employed in step 4 to limit down your search results to the most relevant patent applications by reviewing the abstracts as well as the drawings for each page. Next, carefully examine the patent applications that have been published with particular attention paid to the claims and additional drawings.

7. Find additional US patent publications by keywords in the PatFT or AppFT databases, searching for classification of non-U.S. patents as per below, and searching non-patent patent disclosures in the literature of inventions using internet 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.
