support his claims that the rights established by this Law have been infringed or are about to be infringed, 
may apply provisional measures or measures for preservi
ng evidence, subject to the protection of 
confidential 
information, thus 
preserve relevant evidence in respect of the alleged infringement, i.e.:
 
1) 
to describe in detail the goods infringing the rights established by this Law and to seize them, or 
only to
 
describe them
;
 
2) 
to seize the products infringing the rights established by this Law 
and, in appropriate cases, the 
materials and 
implements used in the production and/or distribution of these products as well as the 
documents relating 
thereto and to col
lect them
;
 
3) 
to apply other prompt and effective provisional measures provided for in the Code of Civil 
Procedure
.
 
6. 
Provisional measures and measures for preserving evidence may be applied 
without the defendant 
having been notified or heard, in particul
ar where 
any delay would cause irreparable harm to the applicant 
or 
where there is a demonstrable risk of evidence being destroyed.
 
Where provisional measures are applied 
without the defendant having been notified and heard, the defendant must
 
be given not
ice without delay, 
i.e. after the execution of such measures at the latest. At the request of the parties, 
including a right to be 
heard, the provisional measures may be reviewed with a view to deciding, within a reasonable period after 
the notification of
 
application of the measures, whether such measures must be modified, revoked or 
confirmed
.
 
7. 
Where the applied provisional measures or measures for preserving evidence are revoked by the 
court or where they lapse due to any act or omission by the person 
who applied for them, or where a decision 
of the court establishing that there has been no infringement or threat of 
infringement of the rights 
established by this Law comes into effect, or where the person, who has applied for provisional measures 
or meas
ures preserving evidence, does not institute proceedings within a period determined by the court, 
the defendant shall be entitled to request compensation for any injury caused by application of those 
measures
.
 
 
Article 56. 
Corrective measures
 
1. 
The person
s specified in Ar
ticle 52(
1) 
of this Law shall be entitled to apply to the court and request 
that products (goods) be 
recalled, removed from the channels of commerce in such a manner as to avoid 
any harm being caused to the said persons and to ensure the p
rotection of their rights (e.g. to remake the 
infringing goods into other goods or to apply similar measures), or to request that the products (goods), 
which the court has found to be infringing the rights established by this Law and, in appropriate cases,
 
the 
materials and implements principally used in the creation or manufacture of 
the specified objects be 
destroyed
.
 
2. 
The measures referred to in paragraph 1 of this Article shall be applied regardless of other 
requirements of a person, applying for thes
e measures, for compensation of the prejudice suffered as a result 
of the infringement of his rights. Such measures shall be carried out at the expense of the 
infringer, without 
compensating and taking into account 
proportionality between the seriousness o
f the infringement and the 
measure applied as well as the legitimate interests of third parties
.
 
 
Article 57. 
Recovery of material damage
 
1. 
The procedure for recovery of material damage shall be regulated by the Civil Code and this 
Law
.
 
2. 
When assessing the amount of the actual damage (losses) suffered as a result of the 
infringement of the rights established by this Law, the court shall take into account the substance of 
the infringement, the amount of the inflicted damage, lost income, in
curred expenses, and other  
 
23
important circumstances. Profit made by the infringer may, at the request of the persons specified in 
Ar
ticle 52(
1) 
of this Law, be recognized as losses. Goods infringing the rights established by this Law 
may be transferred to t
he holders of those rights upon their request
.
 
3. 
The amount of income lost by the persons specified in 
Ar
ticle 52(
1) 
of this Law shall be set 
by taking into account the amount of income which would have been made if the invention had been 
used legally (i.
e. taking account of the royalties which are usually paid for the legal use of the 
invention), as well as the concrete circumstances which might have created conditions for making 
income (works performed by the subjects of the rights, implements used, nego
tiations for conclusion 
of contracts concerning the use of the invention, etc.)
.
 
4. 
Instead of the recovery of the damage (losses) actually suffered by reason of the infringement 
of the rights established by this Law, the persons specified in 
Ar
ticle 52(
1)
 
of this Law may claim the 
payment 
which would have been due if the infringer had used the invention legally (i.e. had acquired 
permission), and where the infringement has been committed intentionally or through gross negligence 
–
 
the said persons may clai
m up to twice the amount of such payment
. 
 
5. 
Where the infringer did not knowingly, or with reasonable grounds to know, engage in 
infringing 
the rights established by this Law (i.e. there is no fault in his actions), the court may, upon request of the 
per
sons specified in Ar
ticle 52(
1) of this Law, order the recovery of profit made by the infringer. A total 
that the infringer has saved and/or made by infringing the rights established by this Law shall be regarded 
as the profit made by the infringer. The pr
ofit made by the infringer shall be ascertained and recovered 
regardless of whether or not the subject of the rights would have made the same profit as the infringer. 
When ascertaining the profit made by the infringer, the subject of the rights must provid
e only the evidence 
that would confirm the gross income received by the infringer; the amount of net profit of the infringer 
(after deducting the expenses) must be proved by the infringer
.
 
 
Article 58. 
Publication of a judicial decision
 
The court which tak
es a decision on the infringement of the rights established by this Law may, at the 
request of the persons specified in 
Ar
ticle 52(
1) 
of this Law, order the infringer to disseminate at his own 
expense the information 
concerning the adopted decision, includ
ing disseminating the decision in full or in 
part in the mass media or by any other means. A judicial decision or information concerning an adopted 
decision may be announced after the coming into effect of the decision, unless otherwise established by 
the 
court. The manner and extent of dissemination of a judicial decision shall be laid down in this judicial 
decision. The persons specified in Ar
ticle 52(
1) of this Law may request that the infringer pay in advance 
into the bank account, indicated by the cour
t, a sum of money necessary to disseminate the information 
concerning an adopted judicial decision or an adopted judicial decision itself
.
 
 
Article 59. 
Declaration of the fact of non
-
infringement of a patent
 
1. 
Any person concerned shall have the right to 
bring an action requesting the court to establish 
that his activity does not constitute infringement of the patent granted to the proprietor
.
 
2. 
The proprietor of the patent must notify any licensees of the proceedings initiated regarding 
the fact of non
-
i
nfringement of a patent. The licensees shall have the right to participate in hearing of 
such case, unless the licensing agreement provides otherwise
.
 
 
Article 60. 
Application of customs supervision measures
 
Customs supervision measures 
determined by legal acts of the European Union and the 
Republic of Lithuania must be applied to the products (goods) which infringe the rights established 
by this Law and which are imported from third countries to the Republic of Lithuania or exported

the Republic of Lithuania to third countries
