Patentscope - All you need to know about using a WIPO Patent Search - Intellect Vidhya Solutions

An innovation or invention is granted an exclusive right known as a patent. All relevant information about the invention must be included in the patent application. Theoretically, the patent holder has the sole right to prohibit or exclude others from using the idea for financial gain. This is the reason that before applying for a patent it is advisable to conduct a patent search for checking whether the same idea is patented in any other country. The World Intellectual Property rights Organisation (WIPO) was established by UNO comprising 193 nations. WIPO’s goal is to create an equitable and open international intellectual property (IP) system that promotes innovation, rewards creativity, and aid in economic growth. WIPO provides a patent search platform known as “Patentscope”, which facilitates searching different patents.

Steps of Conducting Patent Search In PatentScope

Let us understand the steps in the form of the following example.

Suppose an individual has developed a method for printing solar cells onto aluminum foil at a low temperature using a nanoparticle ink.

Step 1 Identifying central concepts related to the innovation

From the description, central concepts can be: “solar cell” (product), “aluminum foil”, “nanoparticle ink” (used for production).

Step 2 Determining keywords for the search

Finding synonyms and related keywords and phrases will be next step for the concepts identified in the first step. With current scenario following synonym or alternate terminologies can be used i.e. solar cell photovoltaic cell (synonym) nanoparticle suspension (related term) aluminum foil aluminium foil (alternative spelling), metal foil (related term) nanoparticle ink nanoparticle solution (related term),

Step 3 Determine IPC symbols for the search

The pertinent IPC symbols can be identified using some of the words and synonyms found in the previous steps by using the IPC Official Publication (see: www.wipo.int/ipcpub). With respect to current example, searching for the term “solar cell” using the predefined settings yields the IPC group H01L 31/00 as a relevant IPC symbol.

Step 4 Performing first search

It is advisable to keep the first search relatively broad, using (i) the “OR” Boolean operator along with keywords and IPC symbols; and (ii) a wildcard operator to include plural forms of words and phrases. The “International Class” (“IC”) can be used in PATENTSCOPE for restricting the search for IPC symbols. The first search focuses on finding a broad range of patent applications related to the product in question i.e. IC/H01L31/00 OR “solar cell” OR “photovoltaic cell”. This search yields more than 250000 results. Examining the results reveal that they include applications covering not only methods for producing solar cells but also for arranging and using solar cells.

Step 5 Use of Boolean Operators

Considering the results from the primary search, the search should be conducted using more specific search terms along with the “AND” Boolean operator. In order to capture results containing wordings such as “nanoparticle solution” as well as “solution containing nanoparticles,” “NEAR” operator can also be used in order to define the distance between 2 words. For example: (IC/H01L31/00 OR “solar cell” OR “photovoltaic cell”) AND ((aluminum NEAR foil) OR (aluminium NEAR foil) OR (metal NEAR foil)) AND ((nanoparticle NEAR suspension) OR (nanoparticle* NEAR solution) OR (nanoparticle* NEAR ink))

Different Factor’s For Conducting Patent Search In Patentscope

Following are the different factors which can be used to find relevant patents:

• Keywords
• Patent classification
• Dates (e.g., priority date, application date, publication date, grant date)
• Patent reference/identification numbers (patent number, publication number, application number)
• Names of applicants/assignees or inventors

Features of Patentscope

Patenscope provides access to millions of patents/patent applications, including, Regional and national patent databases out of several signatory nations and International Patent Applications submitted under the PCT. Following are the methods to conduct patent search in Patentscope:

1. Simple search

The standard WIPO patent search interface is “Simple Search interface”. Individuals/inventors having minimal training or new to patent searches can use it. Following are few possible applications of the Simple Search Interface:

  1. A subject covered using definitive terms, or a relatively precise notion to restrict the number of results
  2. A particular figure: a mention of a patent document in the news, during a court case, etc.
  3. A person, an innovator, a candidate, etc.
  4. A business, whether out of personal interest, to merge with or acquire another business or monitor a rival’s efforts.
  5. A particular period

Following are the 8 preconfigured search areas accessible in the simple search interface, each with different search criteria:

  1. Front Page: Only the document’s front page will be searched using the search keywords entered on this page.
  2. Any field: Using the search criteria provided in this form, any field in the document is searched.
  3. Full text: Enter your search term here if you’re interested in a full-text search.
  4. English text: Records with English text will be looked for using the criteria listed below.
  5. ID/Number: You can include your publication or filing number here.
  6. International Patent Code: In this field, enter any IPC.
  7. Names: List the applicant’s, creator’s, company’s, etc., names.
  8. Dates: Enter any dates you choose
  9. Advanced search – Individuals with appropriate experience and expertise in patent searches can use advanced search interface. Using an infinite number of words, this interface may be used to generate sophisticated search queries.

The interface provides a plurality of field codes and operators, such as Boolean operators, proximity operators, and range operators, which can be used to combine search keywords. An individual/inventor can alter the output of these operators to get specific outcomes. Further, it also enables individual/inventor to search for variations in phrases based on a similar stem or root by using wildcard operators. Patentscope recommends synonyms, which is the new function in the advanced search, “Expand the query,” assists users in broadening the search.

2. Filed Combination Interface

The field combination interface is important search interface for finding and analysing information about patents in the WIPO Patent search database. Individuals/inventors can organize the search precisely by using specific search terms/parameters in each of the search boxes on this interface. The interface provides a list of pre-set search fields that may be combined based on the users’ requirements. The following example steps illustrate how the Field Combination interface is used:

  1. Selecting the field/fields of interest using the drop-down menu’s arrow;
  2. Using the OR/AND boxes to add or include fields;
  3. The individual/inventors can add or remove fields by clicking on them;
  4. Selecting the language the individual/inventors want to search in 11 language options available;
  5. Selecting the collection of interest using the Add button.

3. Chemical Structure Search

The chemical structure search makes it feasible for individuals looking for chemical compounds to recognize molecules that comprise the desired fragment. Only whole structures could be searched till recent years. A new feature i.e. substructure search has been included, which enables individuals/inventors to enter a sketched sub-structure and search for all entries in the Patentscope. This search helps in creation of breakthrough technology and medications.

Following are the 3 options available in the Chemical structure search:

  1. Convert Structure: With this function, individuals/inventors can select the type of search input they want to utilize, for example- a brand name or a chemical constituent.
  2. Structure editor: This feature allows the individuals/inventors to alter a particular search.
  3. Submitting a Structure: This feature allows individuals/inventors to submit relevant documents which provide chemical descriptions.

Cross-Lingual Expansion Search

Cross-Lingual Information Retrieval (CLIR) tool enables individuals/inventors to broaden their search. Before translating content into 13 different languages, the search tool analyses synonyms for the user’s search terms. An individual/inventor must enter search terms in one of those languages into the search box to access the system’s translation and recommendation functions. This enables the individuals/inventors to get the patents published in each of the 13 languages.

Conclusion

WIPO patent search tool i.e. Patentscope provides that patent information which is accessible to the public to analyse novelty of the invention. The search conducted in Patentscope is utilized to analyse all forms of prior arts in existence and other available materials. The individuals or organizations benefit from this patent searches because they can estimate the worth of possible investments in patents. Hence the Patenscope platform provided by WIPO facilitate individuals through simple search engine and easy steps to ensure whether their ideas are novel. The regular updates in the Patenscope database makes the patent search process more convenient and feasible internationally.

    Copyright Protection for Sound Recordings - Intellect Vidhya

    Understanding Copyright for Sound Recordings

    Copyright for sound recordings is a vital aspect of intellectual property law, protecting the rights of creators and ensuring they maintain control over their work. Sound recordings, whether they are music tracks, podcasts, or other audio forms, are protected by copyright, granting the owner exclusive rights to reproduce, distribute, and publicly perform the work. This article will walk you through the basics of sound recording copyright: what it protects, how a traditional right has evolved into an increasingly important one in digital times and how digital distribution impacts your copyright rights. What is Copyright for Sound Recordings? Copyright for sound recordings refers to the legal protection granted to the specific performance or recording of a sound. This protection is separate from the copyright in the underlying musical composition or lyrics — it covers only the actual recorded sounds. For example, when an artist records a song, the sound recording copyright protects that particular recorded version while composition of music and lyrics are protected by means of their own copyright. Copyright owners of sound recordings have several exclusive rights, including: These rights allow creators to determine how their recordings can be used and for which they will receive royalties if others use the work. Duration of Copyright Protection for Sound Recordings The Copyright Act, 1957 of India governs protection duration for copyright in sound recordings. In India, sound recordings are protected for a period of 60 years from the beginning of the calendar year following the year in which such recording is published. This is also in line with the international framework that India has subscribed to, as a member of Berne Convention. As a result of this protection, sound recordings in India are given a standardised period of copyright that may be slightly different from other jurisdictions but one which generally ensures the robust protection to creative works. How Digital Distribution Impacts Your Copyright Rights? The digital environment has transformed the manner in which sound recordings are distributed and includes online platforms (e.g., streaming, downloads) and social media. This has led to many new opportunities for creators, and at the same time created more complications in copyright clearance. Digital distribution impacts your copyright rights in several ways: The Role of Collective Management Organizations (CMOs) Collective Management Organizations (CMOs), also known as Performing Rights Organizations (PROs), also have a major role in taking care of the Copyright for sound recordings. These organizations collect royalties on behalf of copyright owners when their recordings are played publicly, whether on the radio, in public spaces, or online. Joining a CMO gives creators protection in the form to get paid for using their recordings. They support the enforcement of copyright by monitoring usage, and acting against not authorised uses on behalf of their members Copyright Infringement and Remedies Copyright infringement occurs when someone uses a sound recording without permission, violating the copyright holder’s exclusive rights. Infringement can take many forms, including unauthorized copying, distribution, or public performance of the recording. When infringement occurs, copyright holders have several remedies available: Conclusion Sound recording copyright is an essential tool to defend the interests of its creators as it allows control and benefit their productions. With the evolution of digital distribution, it has become even more critical to understand how here-to-for basic principles affect your copyright rights. Keeping up to date about your entitlements, using copyright aids and working with CMOs will enable creators in their quest to protect against unauthorised use of sound recordings.

    The Basics of a Non-Disclosure Agreement NDA - Intellect Vidhya solutions

    The Basics of a Non-Disclosure Agreement (NDA)

    In a world where more information is everywhere, keeping data safe and secret is imperative. It does not matter if you are an entrepreneur, fellow worker, or business partner in this industry; having good knowledge about the Non-Disclosure Agreement (NDA) is extremely important to secure some of your confidential data. This article explores the very basics of NDAs and why they are important, as well as how they manifest themselves in a variety of different scenarios. What is a Non-Disclosure Agreement (NDA)? A Non-Disclosure Agreement, commonly known as an NDA, is a legally binding contract that establishes a confidential relationship between two or more parties. Parties use an NDA to ensure that information they exchange during their relationship stays out of the hands of unauthorized parties. In general, NDAs are very common in business-related situations, such as those relating to trade secrets and associated information that is valuable, including the methods. Why Are NDAs Important? NDAs are essential for several reasons: 1. Protecting Confidential Information: NDAs protect a company’s confidential information, things like business plans, marketing strategies, financial data and intellectual property. This security is critical to have a competitive advantage and prevent misuse or sharing of key information. 2. Establishing trust: With an NDA in place, parties show their willingness to keep information private which then builds and security. This trust is crucial on collaborations, partnerships and negotiations when sensitive information has to be shared. 3. Legal Recourse: Lastly, a non-disclosure agreement (NDA) serves as a legal tool for pursuing action against anyone who breaches the confidentiality. The remedies available to the party that has not breached include monetary damages, specific performance, or injunctive relief. Key Elements of NDA While NDAs can vary in complexity depending on the situation, they generally include the following key elements: Why are NDA used? NDAs are commonly employed in a wide range of scenarios to safeguard confidential information. They are frequently utilised in business partnerships to enable companies to exchange confidential information without concerns of it being disclosed. During employment, NDAs are put in place to safeguard trade secrets that employees may come across in the course of their work. Mergers and acquisitions also depend on NDAs to safeguard vital information throughout negotiations. When developing new products, NDAs are put in place to prevent suppliers or testers from misusing the information. NDAs are crucial in investment discussions to safeguard business plans and intellectual property, as well as in IP patent agreements to prevent the unauthorised disclosure of innovations. In general, NDAs play a crucial role in preserving confidentiality in various aspects of business and law. Legal Validity of NDAs The legal standing of Non-Disclosure Agreements (NDAs) is rooted in contract law, making them legally binding documents that enforce confidentiality between parties. When properly drafted and executed, NDAs are enforceable in court, allowing the injured party to seek remedies such as injunctions or damages if the agreement is breached. However, for an NDA to hold up legally, it must be clear, reasonable in scope, and not overly restrictive. Courts will also consider the fairness of the agreement, ensuring that it doesn’t impose undue hardship on the parties involved. Conclusion Non-Disclosure Agreements are powerful tools for protecting confidential information and fostering trust between parties. By clearly defining what constitutes confidential information, outlining the obligations of the receiving party, and specifying the consequences of a breach, NDAs help prevent the unauthorized disclosure of sensitive data. Whether you’re entering into a business partnership, hiring employees, or developing new products, understanding and utilizing NDAs can be essential to your success and security.

    Micro Copyright in India: Protecting Small-Scale Creative Works

    In the digital age, the creation and sharing of content have reached unprecedented heights. With the proliferation of user-generated content, short-form media, and the increasing significance of individual contributions to larger works, the concept of “micro copyright” has emerged. Micro copyright refers to the protection of smaller, often more granular, creative expressions. In the context of Indian copyright law, this concept presents unique challenges and opportunities. This article explores the intricacies of micro copyright and the conundrums surrounding its protection in India. Understanding Micro Copyright Micro copyright encompasses the rights associated with smaller creative works such as social media posts, memes, short videos, gifs, and even individual elements within larger works, like specific phrases or designs. These forms of content, while often brief and seemingly inconsequential, can hold significant value and can be the subject of copyright protection. The Legal Framework of Copyright in India The Indian Copyright Act, 1957, primarily governs copyright protection in India. The Act provides protection to original literary, dramatic, musical, and artistic works, cinematograph films, and sound recordings. For a work to be protected, it must be original and expressed in a tangible form. Challenges in Protecting Micro Copyright 1. Originality and Fixation One of the fundamental requirements for copyright protection is that the work must be original and fixed in a tangible medium. This can be challenging for micro content, where the line between original creation and common expression is often blurred. Determining the originality of a tweet, meme, or short video clip can be subjective and contentious. 2. De Minimis Doctrine The de minimis doctrine, which means “about minimal things,” can pose a significant challenge for micro copyright. This doctrine suggests that the law does not concern itself with trivial matters. Small snippets of content might be considered too insignificant to warrant protection, leaving creators without legal recourse for unauthorized use. 3. Fair Use The concept of fair use allows for limited use of copyrighted material without requiring permission from the rights holders. In the context of micro copyright, determining what constitutes fair use can be particularly tricky. For instance, sharing a meme or a short clip might be considered fair use, but if it goes viral and gains commercial value, the original creator might seek protection and compensation. 4. Enforcement and Attribution Even if micro content is eligible for copyright protection, enforcing these rights can be challenging. Monitoring the vast expanse of the internet for unauthorized use of small-scale content is a daunting task. Additionally, the ease with which digital content can be shared and altered complicates the process of ensuring proper attribution and compensation. The Way Forward 1. Clearer Guidelines and Definitions To address the challenges of micro copyright, clearer guidelines and definitions are needed within the Indian Copyright Act. Defining what constitutes a protectable micro work and setting standards for originality can provide better clarity for creators and users alike. 2. Digital Rights Management (DRM) and Technology Leveraging technology, such as digital rights management (DRM) systems and content recognition algorithms, can help creators monitor and enforce their copyright more effectively. These technologies can automate the process of identifying unauthorized uses and facilitate easier enforcement. 3. Education and Awareness Increasing awareness among creators about their rights and the mechanisms available for protecting their content is crucial. Educational campaigns and resources can empower creators to navigate the complexities of copyright law and safeguard their micro creations. 4. Legal Reform and International Cooperation Given the global nature of digital content, international cooperation and harmonization of copyright laws can play a significant role in addressing the challenges of micro copyright. Legal reforms that consider the unique nature of digital content and micro works can provide a more robust framework for protection. Conclusion The rise of micro copyright in the digital era presents a unique conundrum under Indian copyright law. While the current legal framework provides a foundation for protecting creative works, the nuances of micro content require more specific attention and adaptation. By addressing the challenges of originality, fair use, enforcement, and attribution, and by leveraging technology and education, India can better protect the rights of creators in the evolving landscape of digital content.
