These and other aspects will be made more clear in the following description and appended claimed that are accompanied by the accompanying illustrations. Understanding that these drawings depict only a few embodiments of the disclosure and cannot be considered limiting of its scope, the disclosure will be explained with more specificity and detail through use of the accompanying drawings.

In one of the ways that is described in this article, a lock comprises a bolt movable along a first axis between a first locked position and a second, unlocked position, the bolt with a first end and a second end and a pin that is that is in mechanical contact with the bolt; aslider movable along a second axis, which is generally perpendicular to the first axis, and an actuator attached to the slider which shifts the slider along the second axis , in response to a signal from a controller; and wherein the slider is designed to touch the pin while the slider moves, thus moving the bolt.

A spring is a common feature. The spring is placed at the end of the bolt and is in contact with the pin.

A few versions of the spring are geared to force the bolt into the first locked position.

In some embodiments, the bolt comprises an opening in the middle with the slot running across the length of the bolt between the first between the first and second ends of the bolt.

A few variations of the slider are designed to extend at most part-way into the slot within the bolt.

In certain instances, the slider includes an initial end portion, a central part, and a second end portion, and the slider is an inclined surface that extends from the first portion until the central portion.

In certain configurations, it’s possible to connect the actuator to the slider at the second end.

In certain instances, the inclined surface of the slider contacts the pin.

Some embodiments allow the slider to move along the second direction. In this scenario the pin moves along the inclined surface of slider. This moves the bolt from its locked position to its second unlocked position.

Certain versions of the slider feature a first and a second ending, , with the middle portion being between. The widths of the slider at both ends are almost equal, whereas the width of the central portion of the slider is less than the width at either the first or second end.

In some embodiments, the width of the slider narrows from the beginning to the middle of the slider.

In some instances the central part is within the bolt’s slot.

Pins in various forms are designed to touch the slider while it moves.

In certain embodiments the second end of the bolt can be tapered, and the other end can be fitted to engage a locking feature.

In certain embodiments the security feature can be attached to a door which can move to allow access to a locked volume.

The locking mechanism is explained in a different aspect. It consists of an receptacle that has a variety of surfaces, and a door that is an area that can be locked.

In some embodiments, the feature of securement includes an extended portion with a cutout formed therein and the first bolt end is received by the cutout formed in the extending part when the bolt is in its first lockedposition.

In some embodiments, the locking mechanism includes a plunger mechanism disposed proximate one of the plurality of surfaces and the mechanism for a plunger comprises rods and springs that is pushed to extend the rod.

A few designs place the rod in contact with the interior of the door once it is locked shut Some have the spring in a compressed state when the door is closed.

In certain circumstances it is possible to use the spring used to push the door open in the event that it is locked.

What is a patent?

A patent is granted by the government to protect an invention, a patent provides the inventor with exclusive rights to create, use to sell, and promote the invention? society gains when a new technology is introduced to the market. The benefits can be directly realized by people who are able to perform feats previously thought impossible as well as indirectly through the economic opportunities which innovation can bring (business growth, employment).

Patent protection is sought out by many universities and pharmaceutical companies for research and development. Patents can be granted for products, processes, or method of creating new materials. In order to be granted protection under a patent the invention must be innovative, novel, and not obvious to other people in the same subject.

Patents give inventors a reward for commercially successful inventions. They serve as a motivator for inventors to create. Patents permit small and emerging businesses and inventors to know that there’s a good chance they will be paid back for their time, effort, and money invested in technology development. They could earn a decent income from their work.

Patents play a vital role in companies, and they can:

Secure your products and services.

Increase the value, visibility, and attractiveness of your product on the market

Differentiate your business and products from the rest;

Access technical and business knowledge and data;

Avoid the danger of accidentally using third-party proprietary content, or losing your valuable data, original outputs, or another creative output.

Patents transform inventors’ knowledge into a marketable asset that opens up new possibilities for employment creation and expansion of businesses by licensing or joint ventures.

Small-scale businesses with patent protection will be more appealing to investors in the commercialization and development of technology.

Patents can result in the development of new ideas and inventions. This information could encourage creativity and could be eligible for patent protection.

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

Patent-protected technology revenue that is commercially viable can be used for financing technological research and development (R&D) which increases the likelihood of better technology in future.

Intellectual property ownership is a way to convince lenders and investors that there are real opportunities to market your product. One powerful patent may open the door for multiple financing opportunities. Patents and other IP assets as collateral or security for financing. Investors can also see your patent assets to increase the value of your business. Forbes and others have noted that each patent can add anywhere from $500,000 to a million dollars in company valuation.

Startups require a carefully-crafted business plan that builds on the IP to show that your product/service is unique and superior or ingenuous. Investors will also be amazed if your IP rights are secured or in the process to becoming secure, and that they agree with your business plan.

It is essential to protect an invention prior to filing for patent protection. Making an invention public prior to its filing typically devalue its originality and make it patent-infringing. Therefore, pre-filing disclosures (e.g. for test-marketing investors, investors, or for other business partners) should only be filed following the signing of a confidentiality agreement.

There are a variety of patents and knowing these is vital to safeguard your invention. Utility patents cover the development of new methods and machines. Design patents cover ornamental designs. Utility patents are the most beneficial since they shield the owner from copycats and other competition. Patents for utility are usually granted to enhance or modify existing inventions. Utility patents can also be used to enhance or modify existing inventions. A process patent could cover the acts or methods to perform a particular action. However, a chemical composition will include the combination of components.

How long will a patent last? Although utility patents are valid for 20 years from the date of their initial filing, they may be extended by delays at the patent office.

How to Search for Patents

The first step in getting the patent you want is to conduct the patent search. You can do a google patent search or do a USPTO search. Once the patent application has been filed, the product that is covered by the patent application could be described as patent-pending. you can locate the patent application online on the public pair. After the patent office has approved the patent application, you can do a patent number search to find the patent issued which means that your product is now patented. You can also use the USPTO search engine. Check out the following article for more information. A patent lawyer or attorney can help you through the procedure. Patents granted in the United States are granted by the US trademark and patent office as well as the United States Patent and Trademark office. The office also examines trademark applications.

Are you interested in finding other similar patents? These are the steps you should follow:

1. Think of terms that describe your invention according to its function and composition or use.

Write down a concise, but precise description of the invention. Be sure to avoid using terms that are generic such as “device,” “process,” and “system.” Consider synonyms for the terms you initially chose. Then, take note of important technical terms as well as keywords.

Use the following questions to help you determine keywords or concepts.

  • What’s the purpose of this invention? Is it a utilitarian device or an ornamental design?
  • Is invention a way to come up with something or to perform a function? Is it an item?
  • What is the composition and function of the invention? What is the physical makeup of the invention?
  • What is the purpose of the invention?
  • What are technical terms and phrases that define the characteristics of an invention? A technical dictionary can help you find the appropriate terms.

2. Use these terms to find relevant Cooperative Patent Classifications on the Classification Text Search Tool. If you’re unable to find the right classification to describe your invention through the classification’s Schemas of classes (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. Examine 3. Check the CPC Classification Definition for confirmation of the CPC classification you found. If the selected classification title includes a blue square with a “D” on its left, clicking on the link will lead you to the CPC classification definition. CPC classification definitions can help you determine the applicable classification’s scope so that you can select the one that is most appropriate. In addition, these definitions can include some tips for searching and other information which could be helpful for further investigation.

4. Get patent documents using the CPC classification from the Patents Full-Text and Image Database. By focusing on the abstracts and drawings that are representative, you can narrow down your search for the relevant patent documents.

5. Use this selection of the most pertinent patent documents to study each one thoroughly for the similarities to your invention. Be sure to read the claims and specification. It is possible to find additional patents by consulting the patent examiner and the applicant.

6. You can retrieve the patent application that has been published and match the CPC classification you picked in Step 3. It is possible to use the same search strategy as Step 4, narrowing your results to the most relevant patent applications by looking at the abstract and drawings on each page. After that, you must review every patent application that has been published with care with particular attention paid to the claims and other drawings.

7. Locate additional US patents using keywords searching in PatFT or AppFT databases, classification searches of non-U.S. patents per below, and searching non-patent publications of inventions with web search engines. 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.
