This Week's Patent News:

🧑‍⚖️⚖️💥Jury Unanimity Targeted in Patent Appeals Totaling $530 Million – Three federal patent-infringement lawsuits are challenging an East Texas judge’s unconventional jury verdict format, which could impact major companies like Apple Inc., PNC Bank NA, and Ecobee.

🚗📱⚔️How a Decade-Old Patent Dispute Could Upend Uber’s Business – Carma Technology has filed a lawsuit against Uber, alleging infringement on five patents related to ride-sharing technology, potentially reshaping the industry.

❓️📜💣️Patent Blame Game: Are 70% of U.S. Patents Really Defective? – A discussion on patent quality sparked by the confirmation hearing of John Squires, nominee for USPTO Director, highlighting concerns over the high defect rate in U.S. patents.

🏛️🔧🌀USPTO Moves Forward with PTAB Reforms Amid Legal Uncertainty – The U.S. Patent and Trademark Office is advancing procedural reforms for the Patent Trial and Appeal Board, while recent Supreme Court rulings create uncertainty around agency rulemaking.

The brilliance of Drackett’s invention lay in its deceptively simple chemistry. He combined sodium hydroxide (lye) with aluminum chips in a recipe that sounds suspiciously like something you’d find in a mad scientist’s notebook. When lye reacts with water, it generates heat, melting through grease and organic matter like butter on a hot skillet. The aluminum chips? They add a dash of excitement, producing hydrogen gas and even more heat because what’s science without a bit of sizzle?

Drano was an instant hit. Suddenly, homeowners could unclog their pipes without descending into the bowels of their plumbing system. By the time Drano became part of S.C. Johnson & Son in 1992, it had cemented its place in the pantheon of cleaning products.

Today, Drano stands as a testament to human ingenuity and the lengths folks will go to avoid calling a plumber. It’s a little ironic, though: a product designed to tackle the grimiest messes became a sparkling clean success story. Harry Drackett might not have invented the wheel, but he sure got it spinning again.

By enabling a storage controller to organize incoming commands into structured groupings, and to complete them in optimized sequences, Hahn laid the groundwork for more efficient, responsive storage performance across a range of environments, from personal computing to cloud infrastructure.

Hahn also advanced PCIe transaction management with techniques that allow storage controllers to adaptively retry failed transfers using alternate alignments or sizes. This improves reliability and throughput without requiring manual intervention or costly performance trade-offs, critical in latency-sensitive and high-availability systems.

In the space of DRAM-less solid-state drives, Hahn devised a novel approach to managing Host Memory Buffer (HMB) cache. His architecture allows the storage device to maintain a mirrored log of HMB deltas, even when the host link is inactive ensuring that data remains accessible and coherent despite the transient nature of host memory availability.

From protocol-level refinements to system-wide performance strategies, Yehuda Hahn’s inventions reflect a deep understanding of how hardware and firmware can co-evolve. His work isn’t just about storing data, it’s about creating smarter, faster, and more resilient ways to use it.

Born in 1856 in Columbus, Ohio, Granville T. Woods was a self-taught engineer who went on to secure more than 50 patents over his career. His work spanned electric railways, telegraph systems, and safety devices for trains. Among his most notable inventions was the “telegraphony,” which allowed voice communication over telegraph wires, an early forerunner to the telephone.

Dubbed the “Black Edison” by the press, Woods often had to defend his inventions in court, including against Thomas Edison himself, whom Woods defeated in several patent disputes. Despite the racial barriers of the era, Woods established his own company and sold his technologies to major firms like Westinghouse and General Electric.

His 1884 steam-boiler patent may not be his most famous, but it exemplifies his ingenuity in tackling real-world industrial challenges. It’s one more reason Granville T. Woods is remembered as one of the most brilliant and resilient inventors of his time.
