Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
76 words
A film identification method comprising the steps of: providing an undeveloped photographic film with first exposure identification indicia, individual ones of which correspond to individual exposure zones, and positioning said individual ones of said indicia adjacent to the corresponding zones of said film; and providing said film with second exposure identification indicia, corresponding to said first indicia and of a size relatively smaller than the first indicia, positioned within the corresponding exposure zones of said film.
Claim 2
Dependent Claim
76 words
A film identification method comprising the steps of: providing an undeveloped photographic film with first exposure identification indicia, individual ones of which correspond to individual exposure zones, and positioning said individual ones of said indicia adjacent to the corresponding zones of said film; and providing said film with second exposure identification indicia, corresponding to said first indicia and of a size relatively smaller than the first indicia, positioned within the corresponding exposure zones of said film.
Claim 3
Dependent Claim
64 words
A film identification method as recited in claim 1, wherein the step of providing said second exposure identification indicia includes making said second indicia in a size such that when an exposure zone of said film is enlarged and printed, the corresponding one of said second exposure identification indicia does not detract from the subject matter of the print, but can be easily read.
Claim 4
Dependent Claim
38 words
A film identification method as recited in claim 2, wherein the step of providing said second exposure identification indicia includes producing said second indicia with a small background of contrasting color shield to make said indicia more outstanding.
Claim 5
Dependent Claim
35 words
A film identification method as recited in claim 3, wherein the step of providing said second exposure identification indicia comprises forming said second indicia of individual figures made up of alternating dark and light segments.
Claim 6
Dependent Claim
46 words
A film identification method according to claim 1, further comprising providing third indicia, common to all the exposure zones of a film, adjacent the exposure zones of the film for identifying the original roll of film from which short lengths of negative film have been cut.
Claim 7
Dependent Claim
38 words
A film identification method according to claim 5, wherein the step of providing said third indicia common to all the exposures of a film comprises forming said third indicia of at least three letters of the English alphabet.
Claim 8
Dependent Claim
27 words
A film identification method according to claim 5, in which the step of providing said third indicia comprises making a repetition of the individual factory film number.
Claim 9
Dependent Claim
40 words
A photographic film according to claim 1, in which the step of providing said second exposure identification indicia located within the exposure zones includes locating said second exposure identification indicia in at least one corner of the corresponding exposure zones.
Claim 10
Dependent Claim
27 words
A method as recited in claim 1, wherein the step of providing said second exposure zone identification indicia comprises producing figures of alternating dark and light contrast.
Claim 11
Dependent Claim
60 words
A method as recited in claim 9, wherein the step of providing said first exposure identification indicia comprises producing a single alphanumeric figure for each one of the first indicia, and the step of providing said second exposure identification indicia comprises producing a pair of alternating dark and light alphanumeric figures corresponding to each of said first exposure identification indicia.
Claim 12
Dependent Claim
33 words
A method as recited in claim 5, further comprising the step of providing a fourth indicia, corresponding to said third indicia, said fourth indicia being, positioned within the exposure zone of said film.
Claim 13
Dependent Claim
77 words
A photographic film comprising: an undeveloped photographic film strip having exposure zones and areas adjacent said exposure zones; first exposure identification indicia positioned in said areas adjacent said exposure zones, individual ones of said first indicia being associated with separate exposure zones for individually identifying said exposure zones; and second exposure identification indicia corresponding to said first indicia and of a size relatively smaller than said first indicia, said second indicia being disposed within said exposure zones.
Claim 14
Dependent Claim
77 words
A photographic film comprising: an undeveloped photographic film strip having exposure zones and areas adjacent said exposure zones; first exposure identification indicia positioned in said areas adjacent said exposure zones, individual ones of said first indicia being associated with separate exposure zones for individually identifying said exposure zones; and second exposure identification indicia corresponding to said first indicia and of a size relatively smaller than said first indicia, said second indicia being disposed within said exposure zones.
Claim 15
Dependent Claim
54 words
The photographic film as set forth in claim 12 and further including third indicia common to all exposure zones of the film strip for identifying the original roll of film from which short lengths of the film strip have been cut, said third indicia being disposed adjacent the exposure zones of said film strip.
Claim 16
Dependent Claim
24 words
A photographic film as set forth in claim 13, wherein each of said third indicia comprises at least three letters of the English alphabet.
Claim 17
Dependent Claim
15 words
The photographic film according to claim 13 in which all of said indicia are black.
Claim 18
Dependent Claim
19 words
The film according to claim 13, wherein some of said indicia are figures of alternating dark and light contrast.
Claim 19
Dependent Claim
