The invention describes a system and method for choosing a device to target from a larger number of devices that could be used to provide a response from an assistant to an end-user. The system determines that a similar trigger phrase used in an utterance has been heard by multiple devices that are in proximity to one another at around the same time. The devices that are candidates can collect information about attention patterns, such as the eye movements towards a device, to determine which device was most likely recipient of the utterance. The system is able to control the virtual assistant to reply only via the selected device.

The advancements in machine learning, language understanding and artificial intelligence is transforming how people interact with computers. Virtual assistants, such as Siri.TM. Google Now.TM., Amazon Echo.TM. And Cortana.TM., are examples of a shift in human-computer interaction. To aid with specific computer-based tasks, a user might depend on an assistant virtual. The user may communicate with the assistant by saying, “Assistant, schedule a meeting with John Smith Tuesday at 10 11 am.” The virtual assistant uses natural language processing to interpret the user’s spoken command and then executes the user’s request.

Although virtual assistant technology is now accurate, reliable and user-friendly as a method for users to communicate with their surroundings. The user typically wants or requires multi-tasking so that multiple tasks can be accomplished while working in an environment that is in the presence of multiple virtual assistant-enabled devices. Unfortunately, attempting to use the services of a virtual assistant using the same device can cause confusion, and several devices (or additional devices) may attempt to respond to the user. Innovative and better methods for improving these interactions between users and virtual assistants are needed.

According to a first aspect, a system for selecting a computing device that can give access to virtual assistants comprises several processors or one or more machine-readable medium. The instructions include instructions that when executed by any processor, trigger a system to detect the initial spoken utterance recorded as an audio signal by a primary device at a single point. It also includes an activation phrase to engage virtual assistants, and receiving from the primary device a corresponding attention signal. The instructions enable the system to decide, based on the first attention signal it is determined that the first device was the likely intended recipient device of the first trigger phrase, and respond to the initial spoken word by the first device, in response to the determination that the first device was most likely to be the recipient device.

The method of providing access to a virtual assistant through computers includes the following methods: determining the initial spoken utterance that is recorded by a device that is a first one in the form of an audio signal the first time, which includes a trigger phrase that allows you to connect with a virtual assistant and receiving from the device an initial attention signal about the first time. The method further includes making a determination, based on the first attention signal that the first device is the likely to be the intended recipient of the first trigger and then rendering an answer to the initial spoken word through the first device in response to the conclusion that the first device was themost likely intended recipient device.

This Summary is provided to provide a range of concepts in a simplified form , which are further discussed below in the detailed description. This Summary is not designed to highlight the most important features or essential aspects of the claimed subject matter and is not designed to restrict the scope of the claims. In addition the claimed subject matter isn’t restricted to only implementations that resolve the disadvantages mentioned in any part of this disclosure.

What is a patent?

A patent is granted by the government in order to protect the idea. It gives the inventor the exclusive right to develop, utilize and market the invention. Society gains when new technology is introduced to market. These benefits could be realized immediately when people can perform feats previously thought impossible, or indirectly through the opportunities for economic growth that innovation offers (business growth, employment).

Patent protection is sought by many universities and pharmaceutical companies for research and development. Patents are granted for the creation of a product, process or method of creating new materials. To be granted patent protection the invention must be useful, new and not apparent to other people in the same field.

Patents reward inventors who have commercially viable inventions. They provide a reason for inventors to come up with new ideas. Patents allow inventors and small businesses to know that there is an excellent chance that they will be paid back on their time, effort, and money invested in technological development. They could earn a living through their work.

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

Secure your products and services

Increase the visibility and value of your product’s presence on the market

Differentiate yourself and your products from others.

Find out about business and technical information.

Beware of the danger of accidentally using third-party proprietary content, or losing important information, creative outputs, or other creative output.

Patents effectively transform the inventor’s knowledge into a marketable asset, which creates new opportunities for employment creation and business expansion through joint ventures or licensing.

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

Patents can spark fresh ideas and innovative inventions. This information could encourage innovation and may qualify for protection under patents.

Patents are a way to stop untrustworthy third-party companies from earning from the invention’s efforts.

Patent-protected technology revenues that are commercially profitable could be used for financing technological research and development (R&D), which will improve the chances of better technology in 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 could lead to multiple financing opportunities. Patents as well as other IP assets can be used as collateral or as security for debt financing. Investors may also look at your patent assets to boost their valuation of your company. Forbes and other publications have noted that each patent can increase company valuation by anywhere from $500,000 to $1 million.

A well-crafted business plan is essential for start-ups. It must be built on IP and demonstrate the way your product or service stands out. Investors will also be impressed when you prove you have IP rights are secure or is in the process of becoming secure and that they align with your business strategy.

It is important to keep an invention secret until you apply for patent protection. Public disclosure of an invention prior to filing can typically degrade the novelty of an invention and render it patent-infringing. Pre-filing disclosures, such as for investors, test marketing, or other business partners is best done following the signing of a confidentiality agreement.

There are several types of patents. Understanding these is vital to safeguard your invention. Utility patents cover new methods and inventions made by machines. Design patents cover ornamental designs. Patents for utility are the best option to protect the proprietor from copies and competitors. In most cases they are granted for modifications or improvements to existing inventions. Utility patents can also be used to enhance or modify existing inventions. For example, a process patent will cover acts or methods of doing one specific thing, while chemical compositions will comprise a mixture of components.

What is the average length of the patent? Utility patents last 20 years from the earliest filing dates, but their expirations may be extended due to delays in the patent office for instance.

Are you planning to protect your idea? Patents are granted only to the first-to-file applicants which is why you need to file fast. Call PatentPC today to get your patent application filed!

Patent searches are a must when you’re drafting the patent application. This will enable you to discover other concepts and provide an understanding of the potential of them. This can help you limit the extent of your invention. Additionally, you’ll be able to learn about state of the technology in your field of innovation. You’ll get a better understanding of what your idea should be, and you’ll be better prepared for writing your patent application.

How to Search for Patents

A patent search is the first step to getting your patent. You can do a google patent search or do a USPTO search. Once the patent application is filed, the item subject to the application may be referred to as patent-pending and you can find the patent application on a public pair. Once the patent office has approved your application, you’ll be able to conduct an examination of the patent number to find the patent issued. Your product will now be patentable. Alongside the USPTO search engine, you can also utilize other search engines such as espacenet, which is described below. A patent lawyer or attorney can assist you with the procedure. In the US, patents are issued through the US patent and trademark office, or the United States patent and trademark office, which also examines trademark applications.

Interested in finding more similar patents? These are the steps to follow:

1. Think of terms that describe your invention in relation to its intended, composition, or use.

Write down a short and precise explanation of your invention. Do not use generic terms such as “device,” “process,” and “system.” Look for synonyms to the terms you picked initially. Also, make note of key technical terms and key words.

Utilize the following questions to help you determine the keywords or concepts.

  • What is the goal of the invention Is it a utilitarian device or an ornamental design?
  • Invention is a method to come up with something or to perform some function? Are you referring to a product?
  • What is the purpose and composition of the invention? What is the invention’s physical structure?
  • What’s the objective of this invention?
  • What are the technical terms and terms that describe the characteristics of an invention? A technical dictionary will help you locate the right words.

2. These terms will allow you to find relevant Cooperative Patent Classifications using the Classification Search Tool. To find the best classification to your invention, scan the class scheme of the classification (class schedules). Think about substituting the words you use for describing your invention, if you fail to get any results from your Classification Text Search with synonyms like the ones you used in the first step.

3. Go through the CPC Classification Definition to verify the validity of the CPC classification you’ve found. If the chosen classification has a blue box which contains “D” The link to the CPC classification definition will be provided. CPC classification definitions will help identify the specific classification’s scope and therefore you’re sure to select the most pertinent. The definitions could also contain some search tips or other recommendations which could prove useful in further research.

4. The Patents Full-Text Database and the Image Database allow you to find patent documents that are accompanied by the CPC classification. By focusing on the abstracts and drawings that are representative, you can narrow down your search for the relevant patent documents.

5. This selection of patent publication is the best to check for similarities to your idea. Pay attention to the specification and claims. You may find additional patents by consulting the patent examiner and the applicant.

6. It is possible to find the patent application that has been published and fit the CPC classification you picked in Step 3. You may also employ the same method of search that you employed in Step 4 to narrow down your results to the most relevant patent applications by reviewing the abstracts and representative drawings for 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 patent publications by keyword searching in PatFT or AppFT databases, classification searching of non-U.S. patents as per below, and searching for non-patent literature disclosures of inventions using internet 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:
  • 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.
