CLASS 473,	GAMES USING TANGIBLE PROJECTILE
Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This class includes:

Apparatus or means relating to the type of amusement, recreational, or play activities commonly known as games or sports (a) in which one or more players or participants use a ball, missile, stream of water, or any other such body which occupies physical space and can be touched and thereby felt by the one or more players or participants (i.e., a tangible body) such that, during play of a game or sport, the ball, missile, or other such tangible body is thrown, rolled, shoved, impelled, propelled, projected, or otherwise put into motion by a nonexplosive force so as to achieve an objective set forth by rules defined for the particular game or sport and (b) wherein the result of playing such a game or sport can be indicated according to rules defined for the particular game or sport;

Devices which are ancillary or appurtenant to the types of games or sports included herein, unless they are provided for elsewhere.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

This class is specific under Class 463, Amusement Devices: Games, which, in turn, is specific under Class 472, Amusement Devices.

Class 273, Amusement Devices: Games, is currently being reclassified through a series of stages. Upon completion of this reclassification, Class 273 will be abolished and replaced either by Class 473 or by Class 463, Amusement Devices: Games. Until this reclassification is completed, the portions of Class 273 which are relevant to Class 473 are to be considered an integral part of Class 473. Specifically, subclasses 108+ and 317+ of the Class 273 schedule are to be considered as following in hierarchy after the last occurring subclass in the Class 473 schedule. The rest of the subclasses of the Class 273 schedule are, for the most part, to be considered as following in hierarchy after the last occurring subclass in the Class 463 schedule. Also, since Class 273 has not been completely screened for all patents properly classifiable in present subclasses of Class 473, appropriate subclass(es) in Class 273 should be considered for search purposes until such time that Class 273 is finally abolished.

LINE WITH CLASS 463

The relationship between Class 473 and Class 463 is that Class 463 is the residual class for games, while Class 473 provides only for those specific types of games in which a ball, missile, or other such tangible projectile (other than a simulation or representation thereof) is used during play thereof. Accordingly, if a game (or a game component thereof) which uses a ball, missile, or other such tangible game projectile (other than a simulation or representation thereof) during play thereof is claimed or solely disclosed, then classification is in Class 473, otherwise, classification is in Class 463 or in the appropriate subclasses of Class 273, Amusement Devices: Games, which follow behind the subclasses of Class 463. However, note that Class 463 provides for (a) a game apparatus or means which uses a simulation or representation of a tangible projectile (e.g., a light-ray simulation of a projectile, a computer generated representation of a projectile, etc.), (b) a propelled racing game in which an object (often a representation of a horse, vehicle, person, etc.) is propelled during play thereof, and (c) a chance device, either per se or in combination with a game which does not use a tangible projectile, whether or not a projectile is included therein, and even if it is not a game or subcombination element of a game (these are, for the most part, still located in Class 273). See also (4) Note above for further elaboration of exceptions to what is provided for in Class 473.

LINE WITH CLASS 345

See Class 463, Amusement Devices: Games, References to Other Classes, in the Search Class note to Class 345 for an elaboration of the line between Class 345 and Class 463, the parent class for Class 473. A selectively controlled visual display system combined with a game component of a game provided for in Class 473 (e.g., a golf club, golf ball, tennis court, tennis court net, etc.) or with a practice or training device therefor (e.g., a golf club swing training device, baseball bat swing training device, etc.) is proper for Class 473.

LINE WITH CLASS 434

Class 473 and subclasses 108+ and 317+ of Class 273, Amusement Devices: Games, contain devices which are to be used for practice by, or for perfecting the physical skill of, a person who already knows how to play the game, sport, or the like. Class 434 contains devices which are to be used for instructing an unknowledgeable person in some aspect of the game, sport, or the like. A device which is used both for instruction and for practice or perfection of game skills is originally placed into Class 434 and cross-referenced into the Class 463 group of game classes (i.e., Classes 463, 473, or 273).

LINE WITH CLASS 446

Class 446, Amusement Devices: Toys, for a device known as a toy whose principle purpose is for the amusement or recreation of a child. If the device is used for the amusement or recreation of a child and is also a game component (i.e., used in a competition or contest), then it is placed into the Class 463 group of game classes (i.e., Classes 463, 473, or 273).

SUBCLASSES

1	BILLIARDS OR POOL:
	This subclass is indented under the class definition.  Subject matter relating to a game which generally involves a horizontally disposed, planar playing surface bounded and defined by raised carom rails (i.e., bumper rails) for confining on the playing surface a plurality of balls which are being projected over the playing surface either into one another or rebounded off of the carom rails; the playing surface either (a) is continuous and has a continuous carom rail rim so that it is devoid of any pockets or other ball receiving receptacles (i.e., a billiard playing surface) or (b) has one or more pockets or receptacles adapted to receive therein or pass therethrough one or more of the balls (i.e., a pool or pocketed playing surface); in playing the game, at least one ball, commonly known as the cue ball, acts as a secondary projecting device and is used to strike and move over the playing surface one or more of the other balls, commonly known as object balls, which act as targets for the cue ball, the cue ball is first forcibly struck by a player aiming and manipulating a first projecting device, commonly known as a cue or cue stick, so as to project the cue ball either directly into engagement with the one or more of the object balls or by first banking or rebounding it off of one or more of the carom rails and then into engagement with the one or more of the object balls so as to move and either position the object balls in a specified arrangement on the playing surface or to pocket them, whereby the player may achieve a score according to the rules specified for the game. (1) Note. In a game of this type balls are usually used but it is to be understood that ball equivalents may be used in their stead provided that they act, other than the fact that they probably do not roll, in the same manner that balls would in playing the game. That is, the ball equivalents should move one another about over the playing surface and should carom or rebound off of one another or the carom rails in the same manner as balls would. (2) Note. Usually, the initial projecting device (i.e., the cue) used to strike the cue ball is a long, tapering, tipped rod or stick but other types of cues that may be used include a mechanically operated cue, a mallet type cue, etc. SEE OR SEARCH CLASS: 235,  Registers,   for a score totalizing apparatus, per se, intended for use in a game, particularly subclass 91 for a device for operating a register involving a billiards or pool game device.

2	Practice device or device to aid in aiming cue or cue ball during shots (e.g., to assist in bank shots, etc.):
	This subclass is indented under subclass 1.  Subject matter comprising either (a) a means to enable a player to improve or perfect his or her skills in the playing of any aspect of the game, or (b) a means to assist a player in determining the proper alignment or position that the cue device must be in so that the cue ball projected thereby moves in the desired direction, or (c) a means to assist a player in calculating or otherwise determining the direction or angle that the cue ball must be projected in order for it to, in turn, project the desired object ball or balls in the desired direction. SEE OR SEARCH THIS CLASS, SUBCLASS: 42+, for a device known as a cue rest or bridge. Although cue rests or bridges can somewhat be interpreted as assisting the player in aligning the cue during shots, they are not included here because their primary function is to aid in supporting the cue during difficult shots such as ones in which the player has difficulty in extending his or her cue supporting and guiding hand close enough to the cue ball to make a reasonably accurate shot. That is, cue rests or bridges do not primarily function to enable a player to determine the proper alignment or position of the cue or the proper direction or angle that a cue ball must be projected to achieve the desired result. SEE OR SEARCH CLASS: 434,  Education and Demonstration,   particularly subclasses 128+ for a means specifically adapted to teach or instruct a person in some aspect of playing a game which uses a gameboard or table such as chess or checkers, and subclasses 247+ for a means specifically adapted to teach or instruct a person in some aspect of a game or sport which involves physical activity.
