| 20130252769 | RACQUET IDENTIFICATION SYSTEM - A racquet identification system for use with at least first and second racquets supported by a multi-racquet support structure. Each of the first and second racquets includes a head portion. The system includes first and second head cards coupled to the head portion of the first and second racquets, respectively. The first and second head cards include first and second bodies and first and second projections extending from the first and second bodies, respectively. The shape of the first body is similar to the shape of the second body. The first body and the first projection define a first orientation. The second body and the second projection define a second orientation. The first and second orientations are different. The first and second racquets have at least one characteristic that varies between the first and second racquets, and the first and second projections are configured to highlight the characteristic. | 09-26-2013 |
| 20140206482 | RACQUET CONFIGURED WITH FEWER CROSS STRINGS THAN MAIN STRINGS - A racquet including a frame having a head portion coupled to a handle portion, and a string bed of interlaced cross and main string segments. The head portion includes a hoop having inner and outer peripheral walls. The hoop defines a head size having a maximum longitudinal and transverse dimensions, a, and b, respectively. The dimension a is at least 1.2 times the dimension b. The inner peripheral wall includes string holes. The cross segments transversely extend from one of the string holes to another, and the main segments longitudinally extend from one of the string holes to another. The cross segment closest to the handle portion and the end point of the longitudinal dimension, a, closest to the handle portion define a second longitudinal dimension, c. The ratio of dimension a to dimension c is at least 6.5. The string bed has at least one more main segment than cross segment. | 07-24-2014 |

| 20140274495 | TENNIS RACKET - A tennis racket may include a handle with a butt end, and a head configured to support strings. The tennis racket may also include a throat connecting the handle and the head, wherein the racket may have a Power Maneuverability Ratio from about 4500 to about 7915, the Power Maneuverability Ratio governed by the equation: | 09-18-2014 |
| 20150335960 | TENNIS RACKET HAVING AN OPTIMIZED STRIKING AREA - A tennis racket having an optimized striking area made from a frame forming a ball striking portion and a handle, the ball striking portion including vertical and horizontal strings configured so as to form sweet spot areas, and a first horizontal bar integrally attached to the frame perpendicular to the handle, wherein the placement of the first horizontal bar affects characteristics of the sweet spot areas. The tennis racket may also include a second horizontal bar and/or two vertical bars. | 11-26-2015 |
| 20160001138 | RACQUET CONFIGURED WITH FEWER CROSS STRINGS THAN MAIN STRINGS - A racquet includes polyester, monofilament racquet string and a frame extending along a longitudinal axis and including a head portion coupled to a handle portion. The head portion includes a hoop having inner and outer peripheral walls. The hoop defines a head size having maximum longitudinal and transverse dimensions, a, and, b, respectively. The dimension a is at least 1.2 times the dimension b. The inner peripheral wall includes string holes. The string has a diameter within the range of 1.10 to 1.55 millimeters. The string forms a string bed of interlaced main and cross string segments. Each of the cross segments transversely extends from one of the string holes to another, and each of the main segments longitudinally extends from one of the string holes to another. The string bed has at least one more main segment than cross segment. At least one of the main segments contacting the tennis ball exhibits a snap back velocity of at least 1 meter per second. | 01-07-2016 |
