In digital cameras, photoelectric converter members have been created that use silicon as a single element. The silicon that is used in the photoelectric convertor member is the sole material that is held in place to the band gap. A color filter is then created over the photoelectric member. In order to create color images using only one plate, the photoelectric convertor member made of silicon as its single material should arrange red pixels and green pixels according to a surface direction.

In addition when a subject with a higher resolution is imaged by using the photoelectric conversion component, luminance moire or color moire could occur. To suppress luminance moire and color moire the optical low-pass filter is required to be installed in the imager. The resolution will decrease when the optical low-pass filter is installed inside the image apparatus.

Japanese Patent No. Japanese Patent No. 4700947. This patent reveals the photoelectric converter component that permits a silicon film that has green pixels to be placed onto one side. This is how incident light can be absorbed by the siliconfilm that has red and blue pixels. In such a photoelectric conversion member, since pixels that absorb green wavelength exist over the entire surface of the photoelectric conversion member it is possible to have no luminancemoire, and color moire could be substantially suppressed.

The photoelectric conversion component described by ‘947 patent may absorb some blue wavelength as well as the red wavelength. As a result, the colorreproducibility can be reduced as well as the noise resistance in the blue region could be deteriorated and the resolution of the color may be also deteriorated. U.S. Patent Application Publication Number. 2014/118579, also known as the “579application” is a proof of the green pixels signal can be corrected (absorption adjustment) using only one of the blue and red pixels.

The photoelectric conversion component described in ‘579 isn’t possible since the red and blue pixels are placed in a checkered order. Thus, quality of the color and resolution could be affected.

What is a patent?

The government grants patents to safeguard an invention, patents grant the inventor with exclusive rights to use, create and sell the invention? society gains when a new technology is introduced to the market. The benefits may be directly, in that it can allow individuals to achieve previously unattainable things, or indirectly, due to the opportunities for economic growth (business growth and employment) that innovation provides.

Many pharmaceutical companies and researchers at universities seek patent protection for their work and research. Patents can be granted to the physical or abstract nature of a product or process or the method or composition of materials that are new to the field. In order to be granted protection under a patent, an invention must be innovative, novel and not be obvious to anyone else in the same field.

Patents reward inventors who have commercially viable inventions. They are an incentive to inventors to invent. Patents enable inventors and small businesses to know that there is an excellent chance that they will be paid back for their efforts, time and money spent on technological development. This means they will be able to make a living by their work.

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

Make sure you protect your unique products and services

Increase the visibility and value of your products ‘ presence on the market

Make your brand stand out from others.

Access business and technical expertise and other information;

Avoid accidentally using third-party content or risk losing valuable information or creative outputs as well as other outputs.

Patents transform inventor’s knowledge into a valuable asset which opens up new opportunities to create jobs through joint ventures and licensing.

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

Patenting may lead to new ideas and new inventions. This information could encourage the development of new ideas and may be eligible to be protected by patents.

Patents can be used to serve as an obstacle to unscrupulous third parties that profit from the invention’s success.

Patent-protected technology that is commercially profitable could be used to fund technological research and development (R&D) that will improve the chances for better technology in the future.

You can leverage intellectual property ownership to convince investors and lenders that your product is a viable commercial value. A powerful patent can lead to multiple financing opportunities. You can use patents and other IP assets as collateral or security financing. Investors can also see your patent assets in order to boost the value of their company. Forbes and other publications have stated that each patent could increase company valuation by anywhere from $500,000 to $1 million.

A properly-written business plan is essential for start-ups. It should be founded on IP and demonstrate how your product/service is distinctive. Investors are also impressed if you have IP rights are secured or are in the process of becoming secure and if they are supportive of your business strategy.

It is essential to protect an invention prior to filing a patent application. Public disclosure of an invention can be detrimental to its originality and invalidate it. Thus, disclosures that are filed prior to filing (e.g. for testing-marketing investors, test-marketing, or for other business partners) must only be done following the signing of a confidentiality agreement.

There are several types of patents. Understanding them is essential to protecting your invention. Patents for utility are used to protect new processes and machine creations. Design patents cover ornamental designs. Utility patents are the best since they protect the creator from copycats and other competition. They are typically issued to improve or modify existing inventions. Utility patents can also be used to enhance or alter existing inventions. For example, a process patent will cover acts or methods of doing an action, while chemical compositions are a mixture of ingredients.

How long does a patent last? Utility patents last 20 years from the earliest date of filing, however their expiration dates can be extended due to patent office delays, for example.

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

1. Create a list of terms that describe your invention, based on its purpose, composition, and use.

Start by writing down a concise detailed description of your invention. Do not use generic terms like “device”, “process,” or “system”. Consider synonyms for the terms you chose initially. Also, make note of key technical terms and keywords.

To help you find the key words and concepts, try the questions below.

• What’s the goal of this invention? Is it a utilitarian device or an ornamental design?
• Is inventing a method to make something or carry out some function? Is it an item?
• What is the composition of the invention? What is the invention’s physical composition?
• What’s the objective of this invention?
• What are the terms in the technical field and keywords used to describe an invention’s nature? A technical dictionary can assist you to identify the correct terms.

2. Utilize these terms to locate relevant Cooperative Patent Classifications at the Classification Text Search Tool. If you are unable to find the right classification for your invention, scan through the class Schemas (class schedules). If you don’t see any results using the Classification Text Search, you might want to think about substituting the words to describe your invention with synonyms.

3. Examine the CPC Classification Definition to verify the relevancy of the CPC classification you’ve discovered. If the classification you have selected includes a blue square with a “D” to its left, the hyperlink will take you to the CPC classification definition. CPC classification definitions can aid you in determining the classification’s scope so that you can choose the most relevant. Additionally the definitions may include search tips and other suggestions that could be helpful in further study.

4. Find patent documents that have the CPC classification from the Patents Full-Text and Image Database. By focusing your search on abstracts and drawings that are representative you can narrow your search to find patents that are most pertinent to your needs.

5. This list of patent publication is the best to check for similarities to your idea. Pay close attention to the specification and claims. Contact the applicant as well as the patent examiner for any additional patents.

6. You can find the patent application that has been published and fit the CPC classification you selected in Step 3. You can also use the same search strategy that you utilized in Step 4 to narrow down your search results to the most relevant patents by reading the abstracts as well as the drawings on each page. Next, examine every patent application that has been published with care, paying special attention to the claims, and other drawings.

7. You can look up additional US patent publications using keywords searching in AppFT or PatFT databases, and also classification searches to find non-U.S. Patents as per below. Additionally, you can make use of search engines on the internet to find non-patent literature disclosures about inventions. 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:
• European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents. 
• Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
• World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
• Korean Intellectual Property Rights Information Service (KIPRIS)
• State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
• Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
• 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.
