Group I contains the composition claims 1 and 2 which are initially classified in
Class 424, subclass 70.1+ among others (in some instances, different moieties
recited as variables will alter classification)

424, subclass 70.1+
The relationship between Group I and II are product and process of use.
Can the group I compounds be used in a different processes of use?
Is there a reason to request an election of species and how many species are
there?
Can the complete set of claims be searched with one search?
Are the claims generic?
What would the computer based search consist of?
Would the search take any longer to consider all possibilities of all variables?
Is there a difference in the amount of art to be considered?
Does shinier hair and conditioning lifetime extension need consideration? 5

utility for the compounds, dysphoric disorders.
• Stedman’s Medical dictionary defines dysphoria
as a feeling of unpleasantness or discomfort.

Chemical Example 2/Restriction 1
• Claims are related as product (claim 1) and process of use (claim 2).
• Variables:
– R classification differs for C1-6 alkyl, phenyl, or pyridyl
– X classification differs for X=C and X=N
– Y classification differs for saturated, partially-saturated or unsaturated 5-, 6-,
7-membered monocyclic ring containing 0, 1, 2 or three heteroatoms selected
from O, N and S
– R’ classification differs for OC1-6haloalkyl, NHC1-6 haloalkyl or S(=O)C1-6
haloalkyl
• The compound and classification change via substitution of a carbon with N.
• Classification of the moieties for each variable differ.
• Each different variable combined with each moiety of each variable result in a
different compound. Please note the number of different combinations.
• Each different moiety for each variable can result in a different search due to
different classification and specifics of the moiety and required search.
• Result may be requirement for electing a specific moiety for each variable. 8
Example 2 Chemical/Restriction 2
• Variables result in different compounds and classification:
• Compounds above separately classified.
9
Example 2 Chemical/Restriction 3
• Group I, claim 1, the compound.
• Group II, claim 2, the method of use.
• Inventions of Group I and II are related as product and process of use. The
inventions can be shown to be distinct if either or both of the following can be
shown: (1) the process for using the product as claimed can be practiced with
another materially different product or (2) the product as claimed can be used in a
materially different process of using that product (MPEP 806.05(h)). In the
instant case, one or more of the compounds can be used in a process of treating
inflammation which differs treating dysphoria.
• Based on differences in classification of the compounds, an election of species
appears appropriate. have different processes or methods of use, e.g., treating
inflammation as opposed to dysphoria of claim 2.
• In one direction there is rejoinder practice if the product (compound) is elected.
• There were 233,497,792 possibilities. A preliminary search of the core did not
run to completion (too many hits).
• MPEP 803 - Burden - criteria are any one or more of separate classification,
10
separate status in the art, or different field of search (MPEP 808.02).

Example 3 Biotechnology/Restriction 1
•
Group I is a noncytotoxic mutant of protein X where the N-, C- and other residues are
altered, are classified in class 530 subclass 324. Claim 1 is a genus type claim which can
also be considered a linking claim.
•
Group II comprises bacterial, fungal, animal or plant or protoplasts containing a vector
with DNA encoding a mutant protein X classified in Class 536 (subclass 23.1+), Class
435 subclasses 320.1 and 325+; and, a method of producing mutant protein X comprising
culturing the host cells for a time and under conditions effective to express protein X and
isolating said protein X from said cells classified in Class 435 subclass 69.1+.

wildtype protein X and thereby lower the amount of cellular protein X classified in Class
424 subclass 130.1.
Independent of the election of one of Groups I through III, an election of species is
required. Each position (N-, C-, 1, 13, 19, 31, or 57) that is changed in amino acid
sequence compared to wildtype protein X needs to be identified by a specific amino acid
residue and/or codon in the case of invention II.
13
Example 3 Biotechnology/Restriction 2
•
Groups I and II; and, I and III are directed to different products. Each is
differently classified and searched (Groups I, II, and III). Neither mutant protein
X nor a Mab substitute for the DNA, vector and host cell. Mutant protein X
and a Mab are different proteins with different chemical, physical, and
biological properties and functions.
•
Group I and II are related as product and process of making. The mutant protein
can be made by traditional chemical synthesis (alternate method of making).
•
Group I is a mutant protein X whereas Group IV is a method of administering
MabX to bind wildtype protein X and thereby lower the amount of cellular
protein X - the method of IV is not indicated in the claim to alter level(s) of
mutant protein X.
•
Independent of the election of one of Groups I through III, an election of species
is required. Each position (N-, C-, 1, 13, 19, 31, or 57) that is changed in amino
acid sequence compared to wildtype protein X needs to be identified by a
specific amino acid residue and/or codon in the case of invention II.
•
Searches for Group I through IV are different. Protein databases (I and III) v
nucleotide databases (II) and one protein v 4 proteins forming one (1) Mab.

themselves fully complementary to a 60-mer of SEQ ID
NO:1.

respectively of the 60-mer SEQ ID NO:1.
• SEQ ID NO: 2 through 6 have a 10 bp overlap with the

Example 4 Biotechnology/Claims
Claim 1. An antisense sequence 20 nucleobases in
length having full-length complementarity within
nucleotides 1 to 60 of SEQ ID NO:1.
Claim 2. The antisense sequence of claim 1,
wherein the antisense sequence has a nucleotide
sequence consisting of SEQ ID NO: 2, 3, 4, 5, or
6.

Claim 1 as presented does not per se claim SEQ ID NO:1 but 20-mer fragments of SEQ
ID NO:1. This is a genus type claim which can also be considered a linking claim for
claim 2.
Claim 1 has all 20-mers of the 60-mer which is SEQ ID NO:1.
In claim 2, all antisense sequences are considered distinct and different from each other
regardless of overlap, since:
– one sequence does not render another obvious
– while they overlap, the overlap does not constitute a common core structure, (such as
a consensus sequence) related to its function
All antisense sequences of claim 2 are embraced by generic claim 1, and are thus subject
to rejoinder should claim 1 be found allowable.

SEQ ID NO: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 are Hc variable regions of Ab# 1 to 10. SEQ
ID NO: 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20 are Lc variable regions of Ab# 1 to 10.
Complementary-determining regions (CDRs) of heavy chains and light chains of the
Abs##1-10 are determined and the residues corresponding to each of the 3 heavy chain
and light chain CDR1, CDR2, and CDR3 are identified and listed in the specification.

Undesired Condition and the sub-genus of Undesired Sub-Condition A and Undesired
Sub-Condition B. The specification teaches the Abs to Novel Protein X can be used to
treat the Undesired Condition, the Undesired Sub-Conditions A and B, and specifically
Disease I, Disease II, Disease III, etc.

Relationships:
– Product I (Ab) and product II (DNA, vector, Host cells) are distinct/different products
not substitutable, different classification and search. Product I can be make, e.g., by
traditional chemical synthesis which is an alternative of the process of II.
– I is related to III and to IV as product and process of use where III and IV demonstrate
alternative processes of use
– II compared to III and to IV are different methods - II is a method of producing the Ab
used in the process of use III or IV. No DNA, vector, or host cell of II is used in the
processes of III or IV.
– III and IV are distinct, different processes with different steps and outcome. The
practice of III does not result in the practice of IV.
Specie election: absent evidence to the contrary, in this instance, each heavy chain and
each light chain pair is a distinct/different Ab on the basis of at least structure and binding
specificity.
Claim 1 as presented is in Markush format but as written only needs one (1) sequence
(need dimer of one Hc and one Lc to make Ab).
Claim 9 and 10 are genus and species.
