Systems, methods and devices are available to minimize the risk of image burn-in on electronic displays. Electronic devices like this may include an image processing circuitry and an electronic display. Image processing circuitry could be able to receive images and examine the image data for potential risk of image burn-in, and, based at least partly on the analysis of the data in the image, decrease the chance of burning-in at least in part , by cutting down the local maximum brightness of the pixel within at least one of a plurality of regions of the image data over time, or by reducing a dynamic range headroom of the image data. The electronic display could display the image data in a manner that has less risk of image burn-in on the pixels of the electronic display.

This disclosure deals with adjusting image data to mitigate image burn-in on pixels of an electronic display.

This section is intended to provide the reader with diverse aspects and claims of art that may be related to the various aspects of current techniques. This discussion will provide background details that could be used to help the reader better comprehend the different aspects of this disclosure. These statements should not be considered to be prior art admissions.

A variety of electronic devices like televisions, portable phones wearable devices, computers, car dashboards, virtual reality glasses, and others–have electronic displays. As electronic displays get greater resolutions and dynamic ranges they are also vulnerable to display artifacts as a result of burn-in of pixels. Burn-in occurs when pixels diminish over time after emitting a particularly high amount of light over a period of time. The image data can be modified in time to accommodate for burn-in to prevent artifacts from appearing on electronic displays. While this may prevent certain visual artifacts caused by burn-in from appearing, it will not always stop the burn-in effect.

What is a patent?

Granted by the government to safeguard an invention, a patent provides the inventor with exclusive rights to create, use, sell and promote the invention? society gains when a new technology is introduced into the marketplace. These benefits may be directly realized as individuals are able to accomplish previously unattainable feats or indirectly, through the opportunities for economic growth that innovation provides (business growth, employment).

Patent protection is demanded by a variety of pharmaceutical companies and university researchers for research and development. Patents can be granted for products, processes, or method for making new materials. To be granted patent protection, an invention must be useful or novel, as well as not obvious to other people within the same area.

Patents reward inventors for their commercially successful inventions. They act as an incentive for inventors to come up with new ideas. Small businesses and inventors can be assured that they will get the most return from the investment they make in technology development through patents. This means they will be able to earn a living from their work.

Companies that are able to:

Protect the latest products and services;

Enhance the visibility and worth of your product’s presence on the market

Stand out and differentiate yourself and your product from the competition.

Access to business and technical knowledge and information;

Avoid using content from third parties or you could lose valuable data or creative outputs as well as other outputs.

Patents effectively transform the inventor’s information into a tradeable asset that opens up new possibilities for employment creation and business expansion by licensing or joint ventures.

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

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

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

Patent-protected technology that is commercially profitable could be used for financing technology-related research and development (R&D), which increases the likelihood of a better technology in the near future.

You can leverage the intellectual property rights of your company to convince lenders and investors that your product has real commercial potential. A single patent could provide numerous financing options. Patents as well as other IP assets are able to be used as collateral or as security to finance debt. Investors are also able to view your patent assets in order to increase their company valuation. Forbes and other publications have stated that each patent could increase company valuation by anywhere from $500,000 to $1 million.

A well-written business plan is vital for start-ups. It should be built on IP and demonstrate the way your product or service is distinctive. Investors will also be impressed when you show that your IP rights are secure or are in the process of becoming secure, and that they align with your business strategy.

It is vital to keep an invention secret prior to filing for patent protection. The public disclosure of an invention could be detrimental to its originality and render it invalid. Therefore, pre-filing disclosures (e.g., for test-marketing investors, test-marketing, or for other business partners) must only be done upon signing a confidentiality contract.

There are many types of patents. Understanding them is crucial to safeguard your invention. Patents for utility are used to protect the development of new methods and machines. Design patents cover ornamental designs. Patents for utility are the most effective since they protect the owner from copycats as well as other competition. Utility patents are often issued to improve or alter existing inventions. Utility patents can also be used to cover improvements and changes to existing inventions. For instance, a process patent will cover acts or methods of doing a specific act, whereas a chemical composition will include the combination of ingredients.

What is the typical length of a patent? Patents that are utility-related last for 20 years from the earliest date of filing, however their expiration dates can be extended due to delays in the patent office, for example.

Are you interested in patenting your ideas? Patents are granted only to the first applicants to file which is why you must file as quickly as possible. Call PatentPC today to get your patent application submitted!

Patent searches are an essential step when you’re writing an application for patent. This will allow you to discover other concepts and provide insights into them. This allows you to limit the extent of your idea. Furthermore, you’ll learn about state of the art in your field of invention. This will allow you to know the extent of your invention and prepare you for filing your patent application.

How to Search for Patents

A patent search is the first step in obtaining your patent. You can do a google patent search or do a USPTO search. Patent-pending is the term for the product covered by the patent application. It is possible to search for the public pair to locate the patent application. When the patent office has endorsed the application, you will be able to conduct a patent number search to locate the issued patent which means that your product is now patented. In addition to the USPTO search engine, you can use other search engines, such as espacenet, as detailed below. Patent lawyers or a patent attorney can help you through the procedure. In the US, patents are granted by the US trademark and patent office or the United States patent and trademark office, which also examines trademark applications.

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

1. Create a list of terms for your invention according to its function composition, use, or purpose.

Write down a short and precise description of the invention. Avoid using generic terms like “device”, “process,” or “system”. Look for synonyms to the terms you initially chose. Then, note significant technical terms and key words.

To help you recognize terms and keywords, you can use the following questions.

  • What is the objective of this invention? Is it a utilitarian device or an ornamental design?
  • Is invention a way to make something or carry out an action? Is it a product or process?
  • What is the purpose and composition of the invention? What is the physical composition of the invention?
  • What’s the objective of the invention?
  • What are technical terms and keywords that describe the essence of an invention? A technical dictionary can assist you to identify the correct phrases.

2. These terms will allow you to look up relevant Cooperative Patent Classifications at Classification Search Tool. To determine the best classification for your invention, scan the classification’s class Schemes (class schedules). Think about substituting the words that you’re using to describe your invention if you don’t receive any results from the Classification Text Search with synonyms such as the terms you used in the first step.

3. Review the CPC Classification Definition for the CPC Classification Definition to determine the accuracy of the CPC classification that you have located. If the classification you have selected includes a blue square with the letter “D” at its left, the link will direct you to the CPC classification’s description. CPC classification definitions can help you determine the applicable classification’s scope, so you can select the one that is most appropriate. The definitions could also contain search tips or other suggestions that can be useful for further investigation.

4. The Patents Full-Text Database and the Image Database allow you to find patent documents that are accompanied by the CPC classification. You can search and find the most relevant patent documents by first focusing on abstract and representative drawings.

5. Take advantage of this list of most relevant patent publications to study each one in depth for any similarity to your own invention. Pay attention to the specification and claims. There are many patents available through contacting the patent examiner as well as the applicant.

6. Find patent applications published in the public domain using the CPC classification you selected in Step 3 in the Applications Full-Text and Image Database. The same method of searching can be used as step 4. You can narrow your search results in order to locate the most relevant patent applications by reviewing the abstracts and representative drawings on each page. After that, take a close look at the patent applications published, paying particular attention to the claims and the additional drawings.

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

  • 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.
