What is a Patent for Mechanical planer and layer are able to make 3-D printed models by using an electrostatic 3-D printer
Three-dimensional (3D) printers have build and support material development stations that can be positioned to transfer layers onto an intermediate transfer surface. The intermediate transfer surface is used to transfer a layer of support and build materials onto a platen each when the platen comes in contact with the transfer surface. The thickness of the layer on a platen is measured by a sensor. The mechanical planer is positioned on the platen to adjust it when the plate moves across the mechanical planeer. A feedback loop is connected electrically to both the sensor and mechanical planer. Based on the thickness of each layer of the platen (determined by the sensor) the mechanical planer alters how much building material as well as support material gets removed.
The systems and methods typically refer to three-dimensional ( 3D) printing processes using electrostatic printing.
Ink-jet printers can be utilized to create objects in three-dimensional printing. One example of this is where a platen moved relative to an inkjet in order to create layers of building material and support material. Each layer is then set by the help of a UV light source. This process is repeated layer-by layer. Support materials typically comprise acid-, baseor water-soluble polymers that are able to be washed off of the build material when 3D printing is complete.
The electrostatic (electro-photographic) process is a well-known means of generating two-dimensional digital images, which transfer materials onto an intermediate surface (such as a photoreceptor belt or drum). Advancements in the way anelectro-photographic image is transferred can leverage the speed, efficiency, and digital nature of printing systems.
Exemplary three-dimensional (3-D) printers include, among other components, an intermediate transfer surface, such as a drum or intermediate transfer belt (ITB), and build and support material development stations positioned to transfer (e.g.,electrostatically or mechanically) build and support material to the ITB. Stations for build and support material developments transfer layers of build and support materials to ITB.
A transfuse station is adjacent the ITB, and a flat platen that has a flat surface is positioned to repeatedly contact the ITB. The platen is moved relative to the ITB and the ITB transfers a layer of the build and support materials to the flat surfaceof the platen at every time that the platen contacts one of the layers of the ITB at the transfuse station to successively form a freestanding stack of the layers that are placed on the flat surface of the platen.
The thickness of the layer on a platen can be determined by a sensor. A mechanical planer is positioned in contact with the platen and level it as the platen passes the planer. The mechanical planer aligns the top of the layer to the flat surface of the platen, and reduces the layer’s thickness. In addition, a feedback loop is connected electrically to the sensor and to the mechanical planer. Based on the thickness of the layers, the sensor determines how much support material and build material is to be removed from each layer. The mechanical planer adjusts the amount of build material and support material based on this information.
In one case, the mechanical planer is an angled blade (e.g. an angled blade that is placed in a non-parallel or non-perpendicular angle with the flat platen surface). Further, such a blade can be moved, as is an actuator attached to the movableblade. The actuator is able to move the knife towards or away from the platen. A cleaning structure is in a fixed place and the structure is able to contact and clean the movable blade as the actuator pushes the blade past thecleaning structure. The structure can also have a collection tray that is adjacent to the mechanical planeer. The collection tray collects the construction material as well as any support material that was removed from the layer of the mechanical planer.
These and other characteristics are described in, or are apparent from the following description.

What is a patent?
The government grants patents to protect an invention, patents give the inventor with the exclusive right to use, create, sell and promote the invention? society is benefited when a brand new technology is introduced into the marketplace. Benefits can be realized in the direct sense, since it may allow people to do previously impossible things, or indirectly by the economic benefits (business expansion and job creation) that innovation provides.
Many drug companies and researchers at universities seek protection under patents for their work and research. Patents are granted for the creation of a product, process or method of creating new materials. Patent protection is granted to any invention that is valuable unique, innovative, and not yet known by other people in the same field.
Patents give inventors a reward for commercially successful inventions. They provide a motivation for inventors to create. Small businesses and inventors can rest sure that they will earn the most return from their investment in technology advancement through patents. They can earn a living from their work.
Patents play essential roles in businesses with the ability to:
Protect new products and services that are innovative;
Enhance the visibility and worth of your products on market
Differentiate yourself and your products from others.
Find out about business and technical information.
Beware of the possibility of accidentally using third-party proprietary content, or losing important information, creative outputs, or any other innovative output.
Patents effectively transform the inventor’s knowledge into a marketable asset which opens new opportunities for job creation and business growth by licensing or joint ventures.
Small-scale businesses with patent protection will be more appealing to investors who are involved in the commercialization and development of technology.
Patents can result in innovations and new ideas. This information can promote creativity and could be eligible for patent protection.
Patents can be used to stop untrustworthy third parties from profiting through the work of inventions.
The profits from technology patents that are successful and commercially viable can be used to fund technological research and development (R&D) and boost the likelihood of improved technology in the near future.
Intellectual ownership of property is a way to convince investors and lenders that there are real opportunities to commercialize your product. One powerful patent may lead to multiple financing opportunities. Patents can be used in conjunction with other IP assets as collateral or security to secure financing. You can also show investors the patents you own to increase the value of your business. Forbes and others have pointed out that each patent can add anything from $500,000 to one million dollars to your company’s valuation.
Start-ups require a well-constructed business plan that leverages the IP to show that your product or service is distinctive or superior to others. Additionally, investors will be impressed if you demonstrate that your IP rights are secure or is in the process of becoming secure and they support your business strategy.
It is important to keep an invention secret until you submit for patent protection. A public disclosure of an invention could be detrimental to its novelty and make it invalid. Thus, disclosures that are filed prior to filing (e.g., for test-marketing, investors, or other business partners) should only be made following the signing of a confidentiality agreement.
There are many kinds of patents. Understanding them is crucial for protecting your invention. Utility patents protect new processes and machine creations. Design patents cover ornamental designs. Utility patents are the best since they protect the proprietor from copycats and other competitors. They are typically granted to enhance or modify existing inventions. Utility patents can also be used to improve or modify existing inventions. For example, a process patent will be able to cover actions or methods for performing one specific thing, whereas a chemical composition will include a mixture of ingredients.
What is the typical length of patents? Patents for utility last for 20 years from the initial filing date, but their expirations may be extended due to delays at the patent office, for example.

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 is filed, the product subject to the patent can be described as patent-pending. you can locate the patent application on public pair. After the patent office approves your application, you will be able do an examination of the patent number to locate the patent that was issued. Your product is now patentable. Alongside the USPTO search engine, you may also use other search engines such as espacenet, which is described below. For assistance, consult an attorney who specializes in patents. Patents granted in the United States are granted by the US trademark and patent office as well as the United States patent office. This office also reviews trademark applications.
Are you looking for similar patents? Here are the steps:
1. Think of terms to describe your invention based upon the purpose, composition and application.
Start by writing down a brief detailed description of your idea. Avoid using generic terms like “device,” “process,” and “system.” Think about synonyms for the terms you picked initially. Then, take note of important technical terms and key words.
To help you recognize 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?
- Invention is a method to make something or to perform an action? Or is it a thing or process?
- What is the composition 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 an invention’s nature? To find the appropriate terms, use an online dictionary of technical terms.
2. Utilize these terms to locate relevant Cooperative Patent Classifications on the Classification Text Search Tool. If you are unable to find the correct classification to describe your invention, scan through the classification’s class Schemas (class schedules) and then try again. Consider substituting the words you use for describing your invention, if you fail to receive any results from your Classification Text Search with synonyms such as the terms you used in Step 1.
3. Examine the CPC Classification Definition to confirm the validity of the CPC classification you have found. If the chosen classification is a blue box that has an “D” to its left, the link will lead you to the CPC classification’s description. CPC classification definitions can assist you in determining the classification’s scope, so you can pick the one that is the most relevant. They may also provide research tips or other suggestions that could be helpful for further research.
4. Retrieve patent documents with the CPC classification from the Patents Full-Text and Image Database. You can look through and find the relevant patent publications focusing first on the abstract and the drawings that are representative.
5. Use this selection of the most pertinent patent documents to study each one in depth for any the similarities to your own invention. Pay close attention to the specification and claims. Contact the applicant as well as the patent examiner for additional patents.
6. You can retrieve patent applications published in the past that match the CPC classification you picked in Step 3. You can apply the same strategy of searching in Step 4 to narrow your search results to the most pertinent patent applications through the abstract and representative drawings that appear on each page. The next step is to review every patent application that has been published with care and pay particular attention to the claims, and other drawings.
7. Find additional US patents using keywords search in AppFT or PatFT databases, classification searches of non-U.S. patents as described below, and searching for non-patent publications of inventions with internet search engines. For instance:
- 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.
