What is a Patent for Conductive PVD stackup design that increase the reliability of electrodes that are deposited
Electronic devices are being design with device portability with a view to portability, for instance, to allow users to use these devices in a wide variety of settings and conditions. These devices are designed to work in various environments and locations. They are also subjected to harsh conditions that can affect traditional and standard electronic devices.
However electronic devices are continuing to include increasingly large numbers of functions, many of which may require the device to interact with, or receive information from, the ambient surroundings. The traditional methods of allowing devices to communicate with its surroundings, like apertures or openings inside the housing, which allow sensors to communicate, can be entry points for contaminants. This can result in the infiltration of unwelcome liquids and abrasive particles within the device. This retention or exposure to the environmental substances or conditions could result in an unintentional amount of degrade in the performance or operation of one or more functions of the device. Additionally, these openings or ports can impact the appearance and style of the device in ways that aren’t pleasing to a user.
It is possible to design alternative components or methods that allow communication between the ambient environment components, devices and components for instance sensors that are contained within the internal volume. These sensors do not have apertures and do not expose any portion of the internal volume to elements.
According to some aspects of the disclosed disclosure an electronic device could comprise a housing component that defines an interior surface as well as an exterior surface of the device. A metallic film is formed on the inside surface, and extending atleast partially onto the exterior surface, and a ceramic film is deposited on the exterior surface and at least partly over a portion of the film on the exterior surface. Ceramic film is electrically linked to a portion the metallic film that was placed in the interior.
The electronic device might also include a seal that is able to isolate an inner space from the surrounding environment. The electronic device can also contain an electronic component in the internal space and electrically coupled to the ceramic film, in which the outside surface is exposed to the environment, and the metallic film and the ceramic film form are electrically coupled to the electronic component using the use of conductive ink. The metallic film may contain at least one of titanium or chromium. A carbonitride can be added to the film. The surface inside can have concave geometry, while the exterior surface may contain a convex geometries. Transparent housing components are possible.
A housing for an electronic device may include a conductive coating that is deposited on the first surface of the housing, and then covering at least a portion of the second surface with aceramic. The conductive film and the ceramic film may create an electrically conductive path extending across the firstsurface and the second.
In some instances, the housing can further comprise conductive ink that has been that is deposited on a portion of the conductive film that is deposited on the surface. Physical vapor deposition is a method of depositing at least one of the ceramic films or conductive films. The first conductive layer may be in contact with the first surface, and a second layer can be deposited on the second side at least partially higher than the first. The first layer of conductive material can be created before the second layer, while the ceramic film can be later formed following the first conductive and second layers.
The first layer of conductive material can be as thick as 100 nanometers, while the second film could be as thick as 50 nanometers. Ceramic films can be as small as 1 micron. At least one element of titanium or chromium can be integrated into the material that is conductive. The ceramic material could comprise an nitride that forms the conductive material. An unplanar surface can be utilized as the primary surface. In a CIELAB color space, the ceramic film could have an L* value between 55 and 65.
In accordance with certain aspects, a method for creating an electrically conductive housing component can include depositing a first conductive layer on a first surface of the housing component, then putting a second conductor layer on a second surface ofthe housing component that is opposite to the first surface, the second conductive layer at least partially overlapping the first conductive layer, and then depositing a ceramic film over the second metallic film.
In some examples the conductive layer could include at minimum one element of titanium or chromium and the ceramic layer could comprise a nitride material including at the very least one of chromium or titanium. A housing component may be a primary component of a housing. The method could also be used to seal the interface between the first and second housing components.Click here to view the patent on USPTO website.

What is a patent?
Patents are granted by the government to safeguard an invention. It grants the inventor the sole right to develop, utilize and sell the invention. Society gains when new technologies are brought to the market. The benefits can be in direct terms, as it may allow people to do previously impossible things, or indirectly, through the economic opportunities (business growth and employment) that innovation provides.
A lot of pharmaceutical firms and researchers from universities are seeking patent protection for their research and developments. 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 novel, useful and not be obvious to anyone else within the same field.
Patents recognize and give inventors a reward for commercially successful inventions. They act as an incentive for inventors to come up with new ideas. Small businesses and inventors are assured that they will get the most return from their investment in technology development via patents. It means that they can make a living by their work.
Companies with the capacity to:
Make sure you protect your unique products and services
Increase the value, visibility, and attractiveness of your products on the market
Differentiate yourself and your products from the rest.
Get technical and business information.
Avoid accidentally using third-party content or loosing valuable information, innovative outputs or any other creative output.
Patents transform inventor’s knowledge into a marketable asset, which opens up new opportunities for employment creation through licensing and joint ventures.
Investors involved in the commercialization and development of technology will appreciate small-scale businesses that have patent protection appealing.
Patenting can lead to new inventions and ideas. This information can promote innovation and may qualify for patent protection.
Patents can be used to prevent untrustworthy third parties from profiting from the invention’s efforts.
Patent-protected technology revenue that is commercially viable can be used to finance technology-related research and development (R&D) which can increase the chance of a better technology in the near future.
Intellectual property ownership can be used to convince investors and lenders that there are genuine opportunities to commercialize your product. One powerful patent may provide many financing opportunities. You can use patents and other IP assets as collateral or security to secure financing. Investors can also see your patent assets to increase the value of your company. Forbes and others have noted that each patent can add between $500,000 and a million dollars in company valuation.
Start-ups need a well-constructed business plan that is built on the IP to prove that your product/service is unique, superior, or innovative. Investors will also be impressed if you can prove that your IP rights are secured or on the verge of becoming secure, and that they align with your business strategy.
It is essential to keep an invention hidden until you file for patent protection. A public divulging an invention could be detrimental to its novelty and invalidate it. Therefore, prior filing disclosures (e.g. for testing-marketing investors, test-marketing, or any other business partners) should only be filed upon signing a confidentiality contract.
There are many types of patents. Understanding them is crucial for protecting your invention. Patents for utility cover processes and machine creations. Design patents cover ornamental designs. Utility patents are the most effective and shield the owner from copycats and other competitors. Patents for utility are usually issued to improve or alter existing inventions. Utility patents can also be used to cover improvements and modifications to existing inventions. A process patent will cover the acts or methods to perform a particular action. A chemical composition will include the combination of ingredients.
What is the typical length of patents? While utility patents are valid for 20 years from the date of the initial filing, they are able to be extended by delay at the patent office.
Do you want to patent your ideas? Patents are granted only to applicants who file first, which is why you must file as quickly as possible. Contact PatentPC now to have your patent application approved!

How to Search for Patents
A patent search is the very 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 protected by the patent application. You can search for the public pair to locate the patent application. After the patent office approves your application, you will be able to conduct a patent number look to discover the patent that was issued. Your product is now patentable. Alongside the USPTO search engine, you may also use other search engines like espacenet as described below. Patent lawyers or a patent attorney can assist you with the procedure. In the US Patents are granted through the US patent and trademark office, or the United States patent and trademark office, which also examines trademark applications.
Are you looking for similar patents? Here are the steps to follow:
1. Brainstorm terms to describe your invention in relation to its intended composition, use, or purpose.
Write down a short and precise explanation of your invention. Avoid using generic terms like “device”, “process”, and “system”. Look for synonyms to the terms you chose initially. Then, take note of important technical terms and keywords.
To help you find terms and keywords, you can use the following questions.
- What is the purpose of the invention Is it a utilitarian device or an ornamental design?
- Does the invention consist of a method of creating something, or fulfilling a function? Does it constitute a product?
- What is the structure of the invention? What is the physical composition of the invention?
- What is the goal of the invention?
- What are the technical terms and keywords that describe the characteristics of an invention? To help you find the appropriate terms, use the technical dictionary.
2. Use these terms to find relevant Cooperative Patent Classifications at the Classification Text Search Tool. If you’re unable to locate the appropriate classification for your invention, look through the class Schemas (class schedules) and then try again. If you do not get results using the Classification Text Search, you may want to consider replacing the words to describe your invention with synonyms.
3. Check 3. Check the CPC Classification Definition for confirmation of the CPC classification you’ve found. The hyperlink to a CPC classification definition will be available when the classification you have selected contains a blue box with “D” on its left. CPC classification definitions will help determine the relevant classification’s scope, so you are certain to choose the one that is relevant. In addition the definitions may include some tips for searching and other information that could be useful for further research.
4. Get patent documents using the CPC classification from the Patents Full-Text and Image Database. You can look through and find the most relevant patent publications by first focusing on abstract and the drawings that are representative.
5. Use this selection of the most relevant patent publications to look at each one in depth for any the similarities to your idea. Pay close attention to the specifications and claims. You may find additional patents by consulting 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 of the Applications Full-Text and Image Database. The same search strategy can be employed as step 4. You can narrow the results of your search to find the most relevant patent applications by looking over the abstracts and representative drawings on every page. Then, you must carefully review the patent applications that have been published and pay particular attention to the claims as well as additional drawings.
7. Find additional US patent publications using keyword searches in the PatFT and AppFT databases, classification searching of non-U.S. patents per below, and searching for non-patent patent disclosures in the literature of inventions using web 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:
- 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.
