Golf Swing Trainer (Watanabe): U.S. and Japanese Patents

What does every golfer really want? Magic golf club? Super golf balls? Not really. What every golfer really wants is a better golf swing. A swing that drives the ball straight down the fairway and onto the green. That’s all. What every golfer really wants is a trainer that keeps his or her arms at exactly the correct position through the entire swing. Not a golf pro to provide criticism – but a trainer to make every swing just right.

This patent family does exactly that by controlling the grip angle created by the arm and golf club shaft! It includes a pair of arm tightening bands (one for each arm), a fastener that ties them to the golf club, a grip angle that is between the left arm, right arm, and the longitudinal length of the golf club, and a string-like member that is attached to the arm tightening bands and restricts the distance between the left and right elbows of the golfer. This invention keeps the golfer’s arms at exactly the right distance from each other through the entire swing, ensuring a more accurate drive! The golfer wears the device while practicing drives to orient his or her arms to the correct distance from each other.

The U.S. and Japan are the two largest markets for golf, so this patent family includes U.S. Patent No. 11,291,903 and Japanese Patent 6644387 for a “Golf swing training tool based on grip angle control” as well as PCT Patent Application 2020152877. This portfolio would be a strategic acquisition for any golf equipment manufacturer or supplier of gold training products.

Solar Powered Electric Bicycle (Lee-Pienkowski): U.S. Patent No. 8,674,571

Bikes are great fun for people of all ages. And in the bicycle industry, electric-powered bicycles (or “eBikes”) are the fastest growing segment. eBikes have electric motors that assist the bicyclist, especially on uphill stretches, from either pedal or handlebar-based thumb controls. However, in order to have your electric bicycle assist at all, the batteries have to be charged. And that means someone has to remember to plug the eBike in at night so it is fully charged in the morning.

Wouldn’t it be great if you did not have to charge your eBike? The invention covered by this patent adds solar panels to the wheels of the eBike, and those photovoltaic cells directly power the electric motor on the bicycle. So, as long as the sun is shining, electrical current is being fed to the bike’s electric motor, assisting the bicyclist. The photovoltaic cells that power the electric motor are rigidly connected to the rotatable element that houses the cells, and the axial shaft is rotatably connected to the electric motor and rigidly connected to a support structure of the rotary object.

U.S. Patent No. 8,674,571 for a “Solar powered wheel apparatus” will enable any eBike manufacturer to offer the next generation of electric bicycles!

Visible Race Start Signal (Santino): Two U.S. Patents

On your mark, get set, go! And a whistle or gunshot starts the race. But what if the swimmer or runner cannot hear the whistle or gun shot? What if he or she has limited hearing, or it’s just too noisy in the arena or gymnasium? There must be a better way to notify swimmers and runners of the start of a race that is effective, fair to all, affordable, and easy to implement.

There is. This portfolio includes a patent that covers technology for light bars that shift through multiple colors – the first tells the athletes to get ready, the second to take their places, and the third to GO! – so all the runners or swimmers are notified at exactly the same time. In a swim meet, a fourth color can be used to aid officials in determining legal turns, exchanges, and finishes. One is mounted at each start point so each runner or swimmer knows the start of the race at exactly the same moment. Auto races have used a similar system for years to communicate with drivers since a whistle or gunshot cannot be heard over the revving engines. There is a second patent for an underwater lap light that notifies swimmers of the last lap in a race.

U.S. Patent No. 10,685,539 for a “Last lap light with extendible pole” and U.S. Patent No. 11,013,977 for a “System and method for athletic competition signaling” would be a critical acquisition for any company supplying competitive sports products and accessories. The system has been approved for use by most athletic organizations including a recent rule change by the NCAA. All the engineering and design work has been done, manufacturing and sales of products have begun, and there are working prototypes, so the company that acquires this technology can go to market with a product line very quickly.

A Better Golf Club Cleaner (Loftus): U.S. Patent No. 10,258,847

Every golfer knows that he must keep his golf clubs clean. Dirt on the surface of the golf club head – especially dirt in the grooves – interferes with a clean strike of the ball. And let’s face it. Every golfer will do whatever she can do to improve her game! Some golf clubs offer buckets of soapy water that the golfers can dip their clubs into, but they do not really do a very effective job of really cleaning the head of the club. What is needed is a compact, affordable, and effective device that will quickly and thoroughly clean golf club heads.

That is exactly what this patent does. It creates a compact device with a cover into which the head of the golf club is inserted, and a combination of soapy water and brushes cleans the golf head. When the golf club is removed, the cover retracts so the water in the device stays clean and does not collect dead bugs and other debris. This patent can be used to create a commercial product for use by golf courses and driving ranges, or a consumer product for personal use. U.S. Patent No. 10,258,847 for a “Golf club cleaning device and method of use” would be a strategic acquisition for any business that is currently supplying products to the golfing community and is looking for a new product category with patent protection through 2036!

Multi-Terrain Golf-Swing Practice Surface (Loftus): U.S. Patent and Trademark Application

When a golfer practices his swing at a drive range there is just one major drawback: The driving range surface is flat. That would be ideal practice if all the courses he played were also flat, but that’s not the case. For truly effective golf-swing practice, a golfer needs to practice on all of the types of surfaces she will be playing on – uphill, downhill, across the upside of a hill, and across the downside of a hill.

This patent addresses exactly that need. It creates a golf-swing practice surface that simulates all the lies a golfer faces – hitting downhill or hitting uphill, and hitting across the upside or, or hitting across downside, of an incline. The device has a base area that is lower than the perimeter sides that slope up from the base, creating a flat surface surrounded by four sloping surfaces. The Field Fairway, a brand the inventor created for the product derived from this patent, can be used in the golfer’s backyard to simulate hitting balls in the rough. U.S. Patent No. 10,786,723 for a “Golf practice device, and method of practicing golf swings by hitting golf balls from replicated sloping topographical conditions, which includes side-hill lies, up-hill lies and/or down-hill lies, encountered on a golf course, off of a simulated fairway and/or a simulated rough” gives any company selling golfing products the ability to introduce a totally new product concept with patent protection for the next 18 years! Also available for acquisition is U.S. Trademark Application 88680435 for “The Field Fairway.”
