Virtual Patent Counsel for Disk-Drive Technology Company

At its peak, the disk drive industry had more than 50 companies, including major players such as IBM, Samsung, Hitachi, Toshiba and others. Today, however, only three firms remain.

We worked with the company from its initial start-up, serving as its virtual in-house patent counsel, developing its patent portfolio, and helping to broadly license its technology. As the industry faced brutal competition and the technology evolved, we worked closely with our client to ensure its patent strategy helped position it for success.

Improving Efficiency, Reducing Costs for Asia-based Client

Patterson + Sheridan manages the patent prosecution process for one of the world’s top 10 U.S. patent issuers. While other law firms might be deterred by language barriers and travel costs, we meet in person with the client on a monthly basis, traveling to Asia regularly to review the inventions covered in their patent filings.

By patiently listening to their input and making strategic use of diagrams, we’ve been able to overcome the language barrier and greatly improve the quality of our client’s U.S. patent filings while at the same time significantly reducing costs. Working directly with the client has also helped us better understand their business and objectives – a critical component for effective representation. 

Our frequent visits and in-person communication have helped us develop closer business and personal relationships with this global technology leader, creating a mutually beneficial model that helps Patterson & Sheridan provide meaningful service to all our international clients.

Closely Partnering with our Client Leads to Multiple Patent Applications and Earlier Filing Dates

sharing ideas

One of our clients, a Fortune 500 equipment manufacturing company, regularly conducts engineering design review sessions that include Patterson + Sheridan attorneys. The client includes us in these sessions to utilize not only our expertise in patent law, but also to increase our understanding of the client’s portfolio as well as the client’s relevant competitors. During the sessions, we capture many concepts that may include patentable subject matter based on our knowledge of the existing art. Additionally, we ask probing questions of the engineers to identify key, distinguishing features that are of potential patentable interest. Based on the discussion from the sessions, we then present to the client multiple patentable concepts with a perspective on how these concepts fit into a larger patent strategy, e.g., alignment with the client’s products and services, as blocking patents, etc. In some cases, the concepts are broadly disclosed in previously filed applications. Therefore, we propose amended, and in some cases divisional, claims to the client. In other cases, we recommend filing new applications.

Our participation results in filing multiple patent applications covering the ideas generated in the brainstorming session. We are able to save money for the client and take advantage of earlier filing dates to block competitors using previously filed applications.

Patterson + Sheridan Team’s Deep ‘Means-Plus-Function’ Knowledge Instrumental in Infringement Suit Dismissal for Large Tech Client

Hammer judge in digital background / Concept of technology lawsuit

Patent law is complex and ever changing, especially in the rapidly growing technology sector. When one of our global clients was sued in federal court along with 14 other defendants for patent infringement, we worked in close collaboration with a joint defense group, taking a strategic approach to resolve a key issue in the case.

Leveraging extensive knowledge in means-plus-function claims, our team was instrumental in presenting arguments that asserted the claims were invalid. While means-plus-function is an area of IP law that is in flux (rules have changed multiple times in the past two decades), the statute allows for claims on functionality when complex, technical devices can be better described by the function they perform versus their structure, materials or equivalents.

Citing specific sections of the statute, we argued that the patent didn’t adequately describe the structure associated with the functions in this claim, rendering it invalid as indefinite (invalidated due to lacking definiteness).

Court-appointed special master validates our argument

Initially, the judge decided that the patent adequately described the structure at hand. But the court appointed a special master to review the claim. The special master agreed with our argument, finding insufficient structure described to support the claim and declaring it invalid as indefinite. The judge ultimately adopted the special master’s recommendation and dismissed the case in the defendants’ favor.

Our team’s knowledge in this complex, ever-changing area of IP law helped the client win the case before having it go all the way to trial. Working with a joint defense group also provided our client and the other 14 defendants with significant savings in avoiding trial.

Using Subject-Matter Eligibility as a Sword and Shield When Protecting Clients’ IP

Patent law is constantly evolving, due in large part to subject-matter eligibility. The latest Supreme Court decision on this subject, known as the “Alice” case (Alice Corp v CLS Bank), held that subject-matter eligibility for claims directed to abstract ideas is based on a two-part test:

  • First: determine if the claims are directed to an abstract idea or general principle.
  • Second: if so, evaluate all claim elements individually, and in combination, to determine if the claims include an inventive concept sufficient to ensure that the patent in practice amounts to “significantly more” than a patent upon the abstract idea itself.

As this area of patent law remains fluid, patent examiners are actively (and inconsistently) using subject-matter eligibility to examine applications. That’s where our vast experience on both sides of the IP process — preparation and prosecution and litigation — becomes a competitive advantage for our clients in industries ranging from computers, the internet, biotechnology, and oil and gas.

Our team has a deep understanding of the level of detail required to ensure a claim is valid when analyzed under the two-part subject-matter eligibility test — even if what we receive from the clients is a high-level description of the invention. We collaborate and dig deep to deliver a more holistic view of our clients’ inventions on the front end, and have developed an arsenal of strategies when drafting applications, including arguments and amendments should a rejection arise.

We’ve helped many of our clients address this issue for years, and their continued business is a testament to our track record in drafting patent applications that can withstand stringent and ever-changing subject-matter eligibility requirements.

Shutting down a patent troll before a costly trial

Building on our experience in drafting solid applications, we also leverage subject-matter eligibility knowledge to defend clients from frivolous infringement claims.

For example, our team represented one of the oil industry’s largest players as lead defense counsel in a multi-party infringement suit brought by a patent troll. Working alongside 12 other firms to represent more than 20 defendants, our deep understanding of subject-matter eligibility was brought to bear against the plaintiff’s broad claim related to “controlling a device over a network.”

Arguing the broadness of the claim and demonstrating that many everyday activities would infringe the plaintiff’s patent — from printing to a network printer to uploading photos to social media sites — our team successfully leveraged the plaintiff to voluntarily dismiss the case at the pleading stage, saving our client and the other defendants from a costly trial.

Resolving a Reissue Standoff: Proving Patent Eligibility in the Face of the ‘Abstract Idea’ Argument

The owner of a 3D printing company found himself in a bind when applying for a reissue of the patent central to his business. Originally filed a decade earlier before the widespread growth of 3D printing, the patent now had some issues that required correcting. However, the view of the law had since changed, and the reissue process hit a standstill.

Fighting for patent eligibility in a changing technology landscape

Statutory law (§35 U.S.C. 101) and case law is limited in defining qualifications for patentable subject matter, particularly in a digital age dominated by software and intangible technology. Legal precedent is scarce, the issue is fluid and examiners are hesitant to pass muster on software-related patents.

In the case of this 3D printing company, the United States Patent Office (USPTO) examiner argued that the basis of the business was too general of an abstract idea to qualify for a patent. (The company offers a user-friendly software that allows consumers to design items to be 3D printed.) The application for reissue stalled — and that’s where the Patterson + Sheridan team came in.

Collaboration, research and a team of uniquely experienced IP lawyers seal the deal

Our attorneys took over the case and got to work immediately, spending hours on the phone with the USPTO examiners. We continually monitor case law to stay on top of new rulings and present new arguments accordingly, and this matter was no different.

This particular patent was a blend of both software (the design program) and manufacturing (the 3D printing), which made it unique. Despite its manufacturing component, the application was still rejected under §35 U.S.C. 101, which is typically reserved for abstract ideas, software and algorithms. Therefore, this type of technology was outside the wheelhouse of the traditional 101 examiners, and it wasn’t the typical patent most manufacturing-focused IP attorneys handle.

However, thanks to our firm’s deep bench of attorneys across a wide range of disciplines, we were able to collaborate and convince the examiners that our client’s idea was indeed patentable subject matter. The patent was allowed and has now been twice examined by the USPTO, making it that much stronger if it’s ever litigated in the future.

Protecting AI-Based Inventions Despite Recent Legal Hurdles

The next wave in technological advancement

Artificial intelligence (AI) is redefining the next technological age. It’s estimated that 38 percent of all businesses are implementing AI in some form, and that adoption rate is expected to increase to 62 percent in 2018. Plus, global revenue from AI-based systems is forecasted to grow from nearly $8 billion in 2016 to more than $47 billion in 2020.

Interest in protecting these inventions is skyrocketing as well. From 2012 to 2017, the USPTO saw a 500-percent increase in the number of patents issuing to class 706 — a classification exclusively designated for AI. But how do you ensure this emerging technology is protected properly?

Overcoming legal hurdles with tailored, detailed patents

Despite recent hurdles put in place by the Supreme Court’s decision in Alice Corp. Pty. Ltd. v. CLS Bank Int’l, AI-based inventions can be protected if you have a knowledgeable, experienced IP legal team focused on this developing market.

At Patterson + Sheridan, we protect AI-based technology by drafting strong patents tailored for these unique inventions. For example, new applications should specifically address the technical problem and technical solution. This is critical to overcome the “significantly more” hurdle in Alice.

Also, when describing the invention in the application, it is crucial to be means-oriented, not only ends-oriented. We avoid the “black box” logic of “input data, processing data, output data,” and instead, provide practical implementation details, such as specifics of the model design. It’s also important to include claim elements that recite specific uses of resulting data, not just the generation of the data.

The right patent attorney makes all the difference

Some are already referring to AI as the “Fourth Industrial Revolution.” This is a pivotal time for software and technology companies who are pioneering in this space — safeguarding those inventions is crucial. Like the revolutionaries who have come before, the leading innovators of this coming revolution should continue to pursue protection of their AI-based intellectual property.

The IP lawyers at Patterson + Sheridan understand the unique challenges of protecting AI technology, and clients appreciate our relentless, hands-on approach. For more of our detailed insights into this topic, read "Smart Strategies for Protecting AI-Based Inventions."
