APPLE INC. (Cupertino, CA)

A chassis can contain a computer system and an input device. The input device could include a sensor, such as an a rod-, pen-or rod-like sensor. The input device can be placed in relation to the chassis in a variety of configurations. The tool may be set away from the chassis and the sensor output of the sensor could create a signal. Another configuration is where the tool contacts the chassis. The sensor output of the tool can produce a second signal as an outcome of inputs to the sensor. An input tool is an example. It can be kept in a recess on a keyboard housing. The recess could generate a first input while the tool is present and a second output when the instrument is removed from the chassis.

There are numerous handheld input devices that can detect user input. For instance styluses are often employed to give input via a digitizer touchscreen panel on an electronic device. The touch panel may include a touch-sensitivesurface that, in response to detecting a touch event, generates a signal that can be processed and used by other components of the electronic device. Display components of the electronic device may display graphic or textual display elementsrepresenting selectable virtual buttons or icons and the surface that is touch-sensitive could allow users to change and navigate the contents displayed on the display screen. The typical user is able to move one or more input devices, for instance, a stylus, across thetouch display in a pattern that can be translated into an input request. Certain styluses are touch or force-sensitive, and be used to input writing or drawing to an electronic device. Remote control of the stylus or electronic device can be accomplished by touching the sensor of the stylus hand-held.

The present invention relates to a computing system which includes a chassis, a computer device, and an input device that includes sensors. In a initial configuration, the input tool can be moved relative to the chassis, but in the second configuration it is not. In the first configuration the input tool can be spaced away from the chassis and the computing device can be set to output a primary signal in response to inputs provided by the sensor. The second configuration allows the input tool to contact the chassis. The computer can be programmed to output a second sign in response to sensor input. However, the first signal is unique relative to the second signal.

In some instances, the input tool is typically rod-shaped. The chassis could include an opening to receive the input tool when it is in the second configuration. The second signal may cause an haptic feedback when placed on the surface of the input tool, or could indicate a scrolling input. The input tool could be positioned at an end of a trackpad within the chassis in the second configuration. The input tool may be placed at the edge of an input device that is key-based that is positioned inside the chassis in the secondconfiguration. When the second configuration is in the input tool is in place, it is able to be placed on the exterior of the chassis.

A further aspect of the disclosure is a computer system that includes a housing with the tool retention section, a keyboard apparatus that is a part of the housing, and a tool removably placed in the tool retention portion. The tool has an object sensor and an electronic component that is in electronic communication that communicates with the sensor. This electronic component can be configured to detect objects in the tool retention area by sending an object sensor signal.

In certain instances, the electronic component can be further configured to change an appearance of a user interface according to detecting the object. A display screen could display the user interface. The user interface can be altered in appearance. interface may involve changing the appearance of the light emitted from the keyboard device. The object sensor can be set to produce the signal in response to the detection of a particular part of the hand of a user. Furthermore, the housing might include a cover that covers the tool to protect it from being displaced in the tool retention section. The object sensor is able to detect the cover and identify the object.

Still another aspect of the disclosure pertains to a device that is user-interface consisting of an input tool with the length, the tip, and a transducer, with the transducer configured to sense an applied force at the tip, and an body for the input device having an input tool retention portion, wherein the input tool can be moved between a first position retained by the body of the input device at the input tool retention portion and an additional position that is separated from the input tool retention area, a source of light withinthe input tool or within the input device body, and an indicator set on the surface of the input tool and spread across the length of the input tool and the set of indicators being illuminated by the light source when the tool in input is in the first position.

The set of indicators could include a set symbol placed across the length of the input tool. A light guide could be inserted into the input device. The guide directs light from the light source towards the set of indicator. The initial row of indicators can extend lengthwise along the initial side of an input tool. A second row of indicators can extend lengthwise along the second side of the input tool. The second side is angularly offset from the first side along a longitudinal axis. Displays that are installed on or inside the surface may illuminate the set of indicators.

What is a patent?

A patent is issued by the government to protect an invention. It grants the inventor the sole rights to develop, use and sell the idea. Society is benefited when new technologies are brought for sale. The benefits can be in direct terms, as it allows individuals to achieve previously impossible things. Or indirectly due to the opportunities for economic growth (business expansion and job creation) that the innovation offers.

Patent protection is sought by a variety of university researchers and drug companies for research and development. Patents are granted to products, processes, or method for making new materials. Patent protection must be granted to an invention that is useful, novel, and not previously known to others in the same field.

Patents reward inventors for their commercially profitable inventions. They act as an incentive for inventors to invent. Small companies and inventors can rest certain that they will receive the most return from their investment in technology development via patents. They can earn a living by their work.

Patents are a crucial part of companies, and they can:

Protect your innovative products and services.

Improve the visibility and the value of your products on market

Your business and your products should be distinguished from the rest;

Access technical and business knowledge and other information;

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

Patents convert knowledge of the inventor into a marketable asset, which opens up new opportunities for job creation through joint ventures and licensing.

Investors in the commercialization and development of technology will find small businesses with patent protection more appealing.

Patents can lead to the development of new ideas and new inventions. This information could be eligible for patent protection.

Patents can be used to prevent untrustworthy third parties from profiting from the invention’s efforts.

Revenues from patent-protected technology that are commercially successful can be used to fund research and development (R&D) and improve the chances of developing better technology in the future.

Intellectual property ownership is a way to convince lenders and investors that there are real opportunities to commercialize your product. Sometimes, a single patent can open the door to multiple financing opportunities. Patents as well as other IP assets are able to be used as collateral or as security to finance debt. Investors may also look at the patents you own to boost the value of their company. Forbes and others have stated that every patent could boost company valuation by anywhere from $500,000 to $1 Million.

Start-ups need a well-constructed business plan that leverages the IP to prove that your product or service is distinctive and superior or ingenuous. In addition, investors will be impressed when you show that your IP rights are secure or in progress of being secure and that they align with your business plan.

It is essential to keep your invention secret until you apply to protect it with patents. The public disclosure of an invention before it is filed can typically devalue its novelty and render it patent-infringing. Thus, disclosures that are filed prior to filing (e.g., for test-marketing, investors, or other business partners) should only be made after signing a confidentiality agreement.

There are many kinds of patents. Knowing the different types of patents is vital to safeguard your invention. Utility patents protect new techniques and machines. Design patents cover ornamental designs. Patents for utility are the most effective because they shield the owner from copycats and other competition. Utility patents are often issued to improve or modify existing inventions. Utility patents can also be used to improve or modify existing inventions. A process patent will be a way to describe the actions or methods of performing a particular act. But, a chemical composition would include the combination of ingredients.

What’s the duration of a patent last? Patents that are utility-related last for 20 years after the earliest date of filing, however their expiration dates may be extended because of delays at the patent office such as.

A patent search is essential when you are drafting the patent application. This will allow you to discover other ideas and give you insight into the potential of them. This can help you restrict the potential of your invention. Furthermore, you’ll learn about state of the art in your field of innovation. You’ll get a better understanding of what your invention ought to be and be more prepared to submit your patent application.

How to Search for Patents

The first step in getting your patent is to do an internet search for patents. You can do a google patent search or do a USPTO search. Once the patent application is submitted, the product that is subject to the patent can be referred to as patent-pending and you can find the patent application on a public pair. After the patent office approves your application, you will be able to do an examination of the patent number to find the patent that was issued. Your product will be patentable. You can also use the USPTO search engine. Check out the following article for more information. For assistance, consult a patent lawyer. In the US patents are issued by the US patent and trademark 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. Brainstorm terms to describe your invention according to its function and composition or use.

Write down a concise and precise description of your idea. Do not use generic terms like “device”, “process”, and “system”. Instead, consider synonyms to the terms you initially chose. Next, note important technical terms and key words.

To help you recognize keywords and concepts, use the questions below.

  • What is the purpose of the invention? Is it a utilitarian device or an ornamental design?
  • Is the invention a way of creating something or carrying out some function? Or is it a thing or process?
  • What is the purpose and composition of the invention? What is the physical structure of the invention?
  • What is the goal of the invention
  • What are technical terms and key words that define the essence of an invention? To assist you in finding the right terms, refer to an online dictionary of technical terms.

2. These terms will enable you to look up pertinent Cooperative Patent Classifications at Classification Search Tool. To determine the most suitable classification to your invention, look through the classification’s class Schemes (class schedules). Consider substituting the words you use to describe your invention if you don’t receive any results from your Classification Text Search with synonyms such as the terms you used in step 1.

3. Check the CPC Classification Definition for confirmation of the CPC classification you’ve found. If the classification you have selected has a blue box with a “D” at its left, clicking on the hyperlink will take you to the CPC classification definition. CPC classification definitions can be used to identify the specific classification’s scope, so you are sure to select the most pertinent. In addition they can provide search tips and other suggestions which could be helpful for further study.

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 look through and select the most relevant patent publications focusing first on the abstract drawings and then on the illustrations that are representative.

5. This list of patent publication is the most appropriate to check for connections to your invention. Pay attention to the claims and specification. There are many patents available by referring to the patent examiner and the applicant.

6. It is possible to find published patent applications that match the CPC classification you selected in Step 3. It is possible to use the same strategy of searching as in Step 4. You can narrow your search results to the most pertinent patent application by looking at the abstract and representative illustrations on every page. The next step is to review the patent applications that have been published carefully, paying special attention to the claims, and other drawings.

7. Locate additional US patent publications using keyword searching in the AppFT and PatFT databases, classification searches of non-U.S. patents as described below, and searching non-patent literature disclosures of inventions using web 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.
