One of the things BHI found from using Santangelo was their ability to adapt copyright law to a very unusual set of circumstances and artwork. We, after all, work with fossils. Probably the best thing about Santangelo Law services is the personal interactions and obvious interest in our products and ideas as well as the ability to brainstorm and adapt to changing circumstances. The friendly atmosphere provided by the staff has been a very important and reassuring aspect of our interactions. I think that Luke surrounds himself with people who like people and are truly interested in helping those people find solutions to their problems.

As a whole, the folks in the office are friendly, trustworthy and are willing to entertain any and all questions. Santangelo has the diversity of expertise, the ability to think broadly about an invention, and the ability to ask the inventor pertinent questions. Moreover, they don't try to push patenting at any cost, but instead make sure that it is the correct business decision for you. Generally, one believes attorneys will intentionally run up charges and always exceed budget numbers. In fact, Santangelo works within a budget, and makes sure one considers the costs and benefits carefully prior to starting a project. Santangelo's services are provided in a very professional yet friendly and honest manner. Services are cost effective compared to many other patent attorneys when one considers breadth of IP, guidance on use of IP and expertise in rendering the original IP in such a way as to minimize further expenses. Santangelo sends out the best Christmas cards ever! We save them and can't wait for the next one!

Santangelo has been a valuable adversary who I have the deepest respect for as a counsel. I learned a lot about a world I did not know, valuing your guidance from start to end. Thank you for your generous assistance in my intellectual property battle. I admire you for your wisdom to make the relationship with your colleague on the other side a big part of your methodology! How come lawyers have such a poor reputation when the profession has people like you?!

Frequently Asked Questions

Common questions about protecting patents, trademarks, copyrights, and trade secrets. Have one that isn't here? Get in touch.

  • What are the different types of intellectual property?
    • Patents protect inventions of new or improved processes, machine, article of manufacture, or composition of matter; new ornamental designs of an article of manufacture, and new plants.
    • Trademarks protect brand identifiers such as words, phrases, symbols, and designs used to identify goods or services.
    • Copyrights protect original creative works such as paintings, computer programs, music, books, and plays.
    • Trade Secrets protect information that has economic value from not being publicly known and is subject to reasonable efforts to maintain it as a secret.
  • What do I need to know about AI and IP?

    Artificial intelligence is rapidly changing the intellectual property landscape, creating both new opportunities and significant legal risks. Businesses and creators should understand that AI-generated content may raise questions regarding ownership, copyright protection, inventorship, confidentiality, and infringement.

    U.S. copyright law generally protects works created through meaningful human authorship, while purely AI-generated works may not qualify for protection. In the patent context, AI cannot currently be named as an inventor under U.S. law. Trademark and brand owners must also be aware of AI-generated misuse of logos, names, and content online.

    Businesses should also be extremely careful about placing proprietary ideas, trade secrets, confidential information, source code, or unpublished inventions into AI chat tools. When using a commercial generative AI platform, users are typically transmitting data to external servers operated by third-party companies. Never assume that an AI interface is private or confidential.

  • What is a patent and what are the different types of patents?

    A patent is a form of intellectual property that provides the patent owner with the exclusive right, for a limited period of time, to exclude others from making, using, selling, offering for sale, or importing a claimed invention. Patents are commonly used to protect new and useful technologies, products, processes, machines, chemical compositions, software-related innovations, and ornamental designs.

    In the United States, the primary types of patents are:

    • Utility Patents protect new and useful processes, machines, manufactures, compositions of matter, and functional improvements thereof.
    • Design Patents protect the ornamental appearance or visual design of an article rather than its function.
    • Plant Patents protect certain new and distinct asexually reproduced plant varieties.

    Additional international filing systems and specialized protections may also be available depending on the technology and countries involved.

  • If I come up with an idea and want to protect it under patent law, what should I do?

    If you believe you may have a patentable invention, it is important to act strategically and protect the idea early in the process. In general, inventors should keep the invention confidential, avoid unnecessary public disclosures, and be cautious about sharing details with third parties without appropriate confidentiality protections in place. Inventors should also avoid entering proprietary invention details into AI chat tools or public generative AI systems, as confidentiality and data retention policies may vary and could potentially impact trade secret rights or future patent protection strategies.

    A patent search and legal evaluation can help assess potential patentability, existing prior art, infringement risks, and available filing strategies. While U.S. patent law may provide a limited one-year grace period following certain public disclosures by the inventor, relying on that grace period can be risky and may significantly limit or eliminate foreign patent rights. Many foreign jurisdictions require absolute novelty and provide little or no grace period after a public disclosure. For that reason, it is often best practice to file a patent application before any public disclosure, sale, offer for sale, publication, or non-confidential discussion of the invention.

  • How long does the patent process usually take?

    The time required to obtain a patent can vary significantly depending on the type of patent, the technology involved, the complexity of the application, the backlog at the patent office, and whether protection is being sought in the United States or internationally. In many cases, obtaining a U.S. patent may take at least one to several years, while foreign patent protection can take even longer depending on the countries involved and the applicable examination procedures. Throughout the process, patent applications are often reviewed through multiple rounds of examination and communications with the patent office before issuance.

  • What is a trademark and can I obtain rights without having to register a mark?

    A trademark is a word, phrase, symbol, logo, design, slogan, or other identifier used to distinguish and identify the source of goods or services of one party from those of others. In the United States, trademark rights may arise through actual use of the mark in commerce, even without a federal registration. These “common law” rights are generally limited to the geographic areas of the country where the mark is used, while federal registration can provide broader nationwide protections and additional legal benefits.

  • What do I need to do before I start using a trademark?

    Conducting a trademark search before adopting or using a mark is important because trademark rights in the United States can arise not only from federal or state registrations, but also from “common law” use based on actual use of a mark in commerce. This means another party may already have enforceable rights in a similar name or brand even if no registration appears in the USPTO database. A comprehensive trademark search can help identify potential conflicts, reduce infringement risks, avoid costly rebranding, and evaluate the availability and strength of a proposed trademark before significant investment is made in marketing, packaging, websites, or product launches.

  • Can I apply for a US trademark registration before I begin using the trademark?

    Yes. In the United States, a trademark application can be filed before actual use through an “intent-to-use” application if the applicant has a bona fide good-faith intention to use the trademark in commerce in the future. However, the trademark will not register until acceptable evidence of actual commercial use is submitted to the USPTO. Filing on an intent-to-use basis may also be a strategic way to begin the registration and examination process before launching a brand, helping identify potential registration issues or conflicts that could create infringement risks before significant time and resources are invested in use of the mark.

  • Why is trademark registration important?

    Trademark registration helps protect brand names, logos, slogans, and other identifiers that distinguish a business’s goods or services. Federal trademark registration may provide nationwide priority rights, public notice of ownership, enhanced enforcement tools, the ability to use the ® symbol, and important legal advantages in infringement disputes. Registration can also strengthen brand value, support licensing opportunities, and help prevent others from using confusingly similar marks.

  • Do I need copyright registration for my work?

    Copyright protection generally exists automatically once an original work is created and fixed in a tangible medium. However, federal copyright registration provides additional benefits, including the ability to file a copyright infringement lawsuit in the United States, potential eligibility for statutory damages and attorney’s fees, and a public record of ownership.

  • Can I protect my patents, copyrights, and trademarks globally?

    Yes. Intellectual property rights can often be protected internationally, but there is no single worldwide patent, trademark, or copyright registration that automatically provides protection in every country. Patents and trademarks generally require country-by-country filings or the use of international filing systems that streamline the application process, while copyrights are often protected internationally through treaties and reciprocal recognition between countries. An effective global intellectual property strategy should evaluate where protection is needed based on manufacturing, sales, licensing, enforcement, and business expansion goals.

  • Who owns a patent, trademark, trade secret, or copyright?

    Ownership of intellectual property depends on the type of asset and the specific circumstances surrounding its creation and use. Patents are generally initially owned by the inventor(s), copyrights by the author(s), trademarks by the party using the mark in commerce, and trade secrets by the person or entity controlling and protecting the confidential information. However, ownership may be transferred or modified by employment agreements, assignments, work-for-hire provisions, licenses, university policies, or other contractual obligations.
