APPLE INC. (Cupertino, CA)
Consumers are choosing intra-canal and intra-concha headphones to enhance listening pleasure when they’re listening music while on the move, or at home. The housings of both electro-acoustic transducerdevices are relatively slim in appearance and contain a driver or receiver (an earpiece speaker). The housing is extremely convenient for the wearer and provides high-quality sound.
Earphones with an intra-canal design are designed to fit into the ear canal and create an ear canal seal. Intra-canal earphones therefore have an acoustic output tube part that extends from the housing. The acoustic tube portion can be inserted into the ear canal of the wearer through the open side. The flexible, resilient tip or cap of the acoustic tube is generally made of silicone or rubber. The tip may be custom molded for the discerningaudiophile, or it may be a high volume manufactured piece. When the tip part is placed into the user’s ear, the tip compresses against the ear canal wall and creates the appearance of a sealed (essentially airtight) space inside the canal. The sealedcavity permits maximum power for sound to be output into the ear canal, it can amplify external sound, thereby decreasing the overall quality of sound.
The intra-concha earphones are inserted into the outer ear and sit above the inner ear canal. Intra-concha earphones do not typically seal within the ear canal and therefore do not suffer from the same issues as intra-canalearphones. Sound quality, however, may not be optimal to the person using them because sound may escape from the earphone, and not reach the ear canal. Additionally because of the variations in ear dimensions and shapes, different amounts of sound may be lost, which can result in inconsistency in sound quality among users.
The invention comprises an earphone housing that has the tip portion that is able to be inserted into the ear canal of the wearer. It also has the body portion extends outward from the tip. A tube section extends out from the body part. A primary output opening for sending sound produced by a driver in the body portion to the ear canal is made in the tip area. An additional outlet opening to vent air to the external environment is created in the part of the body that faces. When the tip portion of the body is placed into an ear canal, the body’s front is positioned in the region of the pinna. The primary output opening and the secondary output opening can be horizontally aligned with one another and facedifferent directions such that they create an acute angle to each other.
The second output port could serve as a leak control port, exposing an acoustic pressure inside the earphone to the external, surrounding environment. In this way the secondary output port could be calibrated to alter an acousticresponse of the earphone. For instance, the secondary output openings could be adjusted to lower the sound pressure at an average of 6 kHz and tune a frequency response of the earphone in order to enhance the overall performance of the earphone.
This summary is not exhaustive and does not encompass every aspect of the invention. It is envisioned that the invention includes every system and method that are practicable from any of the various aspectssummarized above and also those described in the Detailed Description below and particularly pointed out in the claims that accompany the application. Such combinations have particular advantages that are not explicitly mentioned in the previous summary.Click here to view the patent on USPTO website.

What is a patent?
Granted by the government to protect an invention patents give the inventor with the exclusive right to create, use, market and promote the invention? Society gains when a innovative technology is introduced into the marketplace. The benefits can be in direct terms, as it may allow people to do previously impossible things. Or indirectly, through the economic opportunities (business expansion and job creation) that innovation provides.
Patent protection is demanded by many pharmaceutical companies and university researchers for research and development. Patents can be granted for products, processes, or method of creating new materials. Patent protection must be granted to an invention that is useful, novel, and not already known by others in the same field.
Patents give inventors a chance to be recognized for commercially successful inventions. They provide a reason for inventors to invent. Patents permit entrepreneurs and small companies to be confident that there’s a good chance they will be paid back on their time, effort and investment in the development of technology. They can make a living by their work.
Businesses with the ability to:
Secure your products and services
Increase the visibility and value of your product’s presence on the market
Differentiate yourself and your products from the competition.
Access business and technical expertise and data;
Avoid the risk of accidentally using proprietary third-party content, or losing valuable data, original outputs, or another creative output.
Patents can transform an inventor’s information into a tradeable asset which opens new opportunities to create jobs and boost business growth by licensing or joint ventures.
Investors who are involved in the commercialization and development of technology will appreciate small businesses with patent protection to be more attractive.
Patenting can generate new ideas and new inventions. This information can encourage creativity and could be eligible for patent protection.
Patents are a way to stop untrustworthy third parties from making money from the invention’s efforts.
Commercially successful patent-protected technology revenues could be used to finance technological research and development (R&D), which will increase the chance of better technology in the coming years.
You can leverage intellectual property ownership to convince investors and lenders that your product is a viable commercial value. Sometimes, one powerful patent can lead to a variety of financing possibilities. Patents and other IP assets can be used as collateral or as security for financing debt. You can also show investors the patents you own to increase the value of your business. Forbes and others have pointed out that every patent could add between $500,000 and one million dollars to company valuation.
Startups require a carefully-crafted business plan that is built on the IP to show that your product or service is distinctive superior, innovative, or superior. Investors will also be impressed if you show that your IP rights are secure or in progress of being secure and that they are in line with your business plan.
It is important to keep an invention secret until you apply for patent protection. The public disclosure of an invention before it is filed can often destroy its novelty and render it patent-infringing. Therefore, pre-filing disclosures (e.g. for testing-marketing, investors, or other business partners) should only be made upon signing a confidentiality contract.
There are numerous types of patents. Understanding them is crucial for 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 owner from copycats and other competitors. Utility patents are often issued to improve or alter existing inventions. They can also be used to improve or modify existing inventions. A process patent could be a way to describe the actions or methods of performing a specific act. But, a chemical composition would include an amalgamation of ingredients.
What is the typical length of patents? While utility patents are valid up to 20 years from their initial filing, they can be extended by delay in the patent office.
Are you considering the patenting of your idea? Patents are only granted to applicants who file first, so you must file quickly. Contact PatentPC now to have your patent application approved!
A patent search is an essential step when you are drafting the patent application. This allows you to see other concepts and provide insight into their potential. This will allow you to restrict the scope of your invention. It is also possible to learn about the state of the art within your field of invention. This will allow you to know the extent of your invention and prepare for the filing of the patent application.
How to Search for Patents
The first step in getting your patent is to perform an internet search for patents. You can do a google patent search or do a USPTO search. After the patent application has been filed, the item covered by the application can be referred to as patent-pending and you can find the patent application on public pair. After the patent office approves your application, you’ll be able to conduct a patent number look to find the patent issued. Your product now has the potential to be patentable. In addition to the USPTO search engine, you may also use other search engines like espacenet, which is described below. Patent lawyers or a patent attorney can help you through the process. Patents granted in the United States are granted by the US trademark and patent office as well as the United States patent office. The trademark office also evaluates trademark applications.
Are you interested in finding similar patents? These are the steps you should follow:
1. Think of terms to describe your invention based upon the purpose, composition and use.
Write down a short, but precise explanation of your invention. Avoid using generic terms such as “device”, “process,” or “system”. Instead, think about synonyms for the terms you chose initially. Then, take note of important technical terms as well as keywords.
To help you identify 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?
- Is inventing a method to come up with something or to perform some function? Are you referring to a product?
- What is the nature and purpose of the invention? What is the invention’s physical composition?
- What is the goal of this invention?
- What are the technical terms and terms that describe the nature of an invention? To help you find the appropriate terms, use an online dictionary of technical terms.
2. Utilize these terms to locate relevant Cooperative Patent Classifications at the Classification Text Search Tool. To determine the most suitable classification to your invention, scan the class scheme of the classification (class schedules). If you don’t get any results using the Classification Text Search, you may want to consider replacing the words that describe your invention with synonyms.
3. Review 3. Go over the CPC Classification Definition to verify the relevancy of the CPC classification you’ve discovered. The hyperlink to a CPC classification definition is given in the event that the title of the classification is a blue square with a “D” to the left. CPC classification definitions can assist you in determining the classification’s scope of application so that you can choose the most relevant. Furthermore, these definitions can include research tips and other suggestions which could be helpful for 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. You can search and find the relevant patent publications by focusing first on the abstract and drawings representative of.
5. This selection of patent publications is the best to examine for similarity to your invention. Pay attention to the specification and claims. It is possible to find additional patents through contacting the patent examiner and applicant.
6. Search for patent applications that have been published using the CPC classification you selected in Step 3 in the Applications Full-Text and Image Database. You can apply the same search strategy in Step 4 to narrow your search results to the most relevant patent applications through the abstract and representative illustrations on every page. Then, you must carefully review the patent applications published, paying particular attention to the claims and additional drawings.
7. Find additional US patents by keywords in the PatFT or AppFT databases, searching for classification of non-U.S. patents as per below, and searching non-patent literature disclosures of inventions using internet search engines. Here are a few 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.
